I'm watching a dude on UA-cam rewire the engine on his 1990 Hyundai* Stings more when you say it like that, underscoring that it's not some prestine muscle car worth houndreds of thousands or something like that :P
Jafro, you're the man. Hands down you give lots of energy to cars that I didn't consider cool when coming up in the 90's. I can appreciate the time and effort that went into this. Caleb, the world needs Built. Hopefully, you can find it in you to come back.
Okay got one for you! In 1980 My brothers father in law, owned an old Auto car Truck. Wiring was bad, was so old was the cloth covered stuff. Well he had a brother that was visiting him. He was a old man, and had a stroke. That left him with difficulty in use of left arm and other things. The man was a very nice and I like him. Now one day the father in law, he put his brother to work replacing the wire in the truck. I asked my brother what was he thinking? My brother said, don't worry about it. He'll get it done and asked me to keep eye on him and get him anything he needs. So I show him where all the wire was and tools etc. Had, like you every color you could think and in different size. So he went to work replacing the wires. I went on with my work in the shop. Every once in awhile I would look out at him. He was working away, had wire all over on the ground. Late that afternoon I walked over to see how he was doing. And could not belive what I saw... He was replacing each wire, one at a time and was doing good, except he replaced every wire with only white wire and same gage! No colored at all. I did not say anything! As I watched, he was talking, telling me how he had to go to school and took a wire class on this new plastic covered wire. How to cut it, splice it, and crimp it etc. He said, When they came out with it and remembered when was all new stuff. I walked away... found my brother and told him what was happening, and what he told me about school and how long he was in class for it! That's when I found out something about not to judge people, See he was a rocket science engineer, and worked during the war and with NASA building rockets before his stroke. I was shocked! Now the truck did run and everything worked when he was done, just was with only one color of wire. All white, one gage!
There was a time we’re wiring wasn’t colored. Check out old Italian autos and such and you’ll see it’s all exactly the same color. I wonder if the same was true for rockets and such as they are kind of single use.
About 5 years ago I binged watched your channel on a different youtube account and I was waiting for more videos to come out. Then, I got a new youtube account. Finally, in 2023 youtube algorithm got me back here and I couldn't be happier.
Seeing a wire harness done right is a thing of beauty. Most of the time pro mechanics don't even bother using the correct crimping tools or splicing procedures.
@@Jafromobile I did many wiring repairs over those years but nothing even close to what you did, heh navigating Hyundai service info can be a "challenge" eh? (Did almost 4 yrs @a Kia dealer)...killer job dude, most I've done is rewiring/upgrading my old 73 Honda cb750 (added relay ckts for ign n headlamps to take the load off the ign switch). .idk if I would build a harness from scratch like that but...I appreciate seeing you doing it...means we alll can!
Yep!! And, the wire striper tool is pure brilliance. I’ve been scrounging salvage harnesses just to getting the striped wires I need… imagine my storage area
I have just finished installing an entire vehicle wiring harness in A 1977 Chevrolet Step Van Ice Cream truck. Mophorn Wiring Harness Kit 12 Circuit Hot Rod Universal Wiring Harness Muscle Car Street Rod XL Wires. It wasn't the exact harness so I had to remove a couple of the Circuits, then I added and electric Radiator Fan and Music Box and Flip out Warning Sign and Front and Rear Flashing Lights. It took me a lot of notes even with the proper Wiring Diagram and a ton of Pictures. It took me a Month of working a few hours everyday, but everything is working like it's suppose to. I had never done a Full Vehicle Wiring Job before, but it came out working so I am Proud of Myself for doing it.
"cut up more than a magazine in jussie smollett's living room" -- remind me not to eat breakfast cereal when watching your channel. You owe me a new keyboard.
@@ajgonzalez5109 Racism and homophobia are real societal problems in America, sadly even today. But Jussie... Well, read his Wikipedia article. Or watch Dave Chappelle's stand up routine about it.
Your uploads are nothing short of stellar. You deserve to be in the YT automotive content creator Hall of Fame. Not only are your uploads informative and creative, but entertaining as well. One does not have to be specifically tied to JDM products to follow your work. As someone who has followed-subscribed for quite some time all I can say is thank-you for all the effort you put into all your work . You rock Jafro!
Alright, I just watched an hour and twenty two minutes of you doing this wiring. On a vehicle I have absolutely no notion of every purchasing. I must say though, for the black wire being the only cause of the issue you had. PHENOMENAL work good sir!
HECK YEAH! The most consequential imports ever built. I bet all kinds of DSMs are getting fixed right now while everyone's locked down. The only thing that interferes with their maintenance is their owners having a day job.
So I just happened upon this video, but figured I'd pass along some "knowledge" if anyone needed it down the road. There is a place in North Carolina called Miller Import Parts that dismantles DSM's and other cars. Found them when I needed a crossmember for one of my Nissans. Perhaps this will help either or you, or someone else, find parts if they ever need them.
Worth the wait, for sure. As someone who has completely re-wired my own car, converted from a carb to EFI, converted from mass air to speed density, and completely rewired from fuse box to cigarette lighter, I especially admired your attention to detail. It's a long and tedious job. Props to you for actually using the correct factory wire coloring, my junk is a mass of red and black wires! This is by far the best harness wiring project I've seen on the 'net. I'd love to see a before and after picture of some of your log traces to see the difference in noise in the different channels, especially the TPS, MAP and Battery voltage channels. I know my own logs cleaned up quite a bit when I put some attention to the grounds and signal wires. Great job!
That PVC marker holder/striping tool was genius, seriously. I'm a cheap bastard with a Honda, so I usually just get marked wire out of the newest/biggest Honda I can find in the junkyard. I'm also usually only replacing one or two sensors worth of wires that I think need to have the same exact color.
There is NOTHING more satisfying than finishing an engine loom or doing a full proper repair. Personally I prefer TESA high temp loom tape for the ends and corrugated tubing for the trunks. I heat shrink for abrasion if wires come out of the trunk at any point.... great job
I know what you mean about DSM wiring. I used to own an old 88 Dodge Conquest TSi widebody and had nothing but wiring issues with that car. Hats off to you sir for going through all this work 👍🏻
Your WIRE STRIPER is genius and yes I searched online...got distracted by all that stripping...then the other half got home and we got distracted...by the stripping...and that's my excuse for taking 18 months to see this to the end.
Just pulling the old harness out made my head hurt. By the time he unpacked all the tools, wires, connector etc. I had a migraine! Just got done redoing the harness on my sons 4 wheeler and after I was finished I kicked myself in the ass for not just buying a new one, I couldn't imagine even attempting one of this size. Great video funny as hell and really an awesome job.
I'm about to do it again... That's the other downside. Once you've done it, you're less resistant to starting this job up and doing it again. Seriously, read down your bucket list. You'll find this item re-appears. I don't know why it does that? I thought I was finished?!
@@Jafromobile I agree you do become less resistant. I like to leap into the things I'm not completely comfortable with because of the experience and knowledge I usually gain (after alot of swearing). This however was something I definitely wouldn't want to tackle unless I knew that car inside and out which clearly you do. Great job I look forward to the next one.
I’m a woman so it’s harder for me to find what I’m looking for in my late 60’s u have done a great job addressing everything in ur video ty !! I’m Still trying to save money by doing my own van repairs
Wiring is like porn to me being an automation electronics engineer. Watching it done at this detail and with Jafro's easily comprehending explaination for as long a movie lasts... was the high point of the quarantine!
"Just buy a harness, if you can it is cheaper" Naw, now you know everything there is to know about your electrical system, what goes where, why it goes there. This is super valuable info, that can only be understood by making your own harness.
This is probably one of the best cable porn movies: - Unnessasry chatty parts fastforwarded - Good quality strippers and properly cut dongles - Kinky harnesses/whips - Money shot at 1:17:52
I just bought a 77 dodge truck and wanted to fix the mess the old owner has...and you answered my hours of searching for colored stripped wires ....thanks
I apologise now, I couldn’t help but smile when you SIGHED at the beginning, I think we’ve all been there at some point. Great content as ever, prefect isolation entertainment.
I’m as relieved as you are that your harness worked and going through all the struggles. You’re far more patient than I am. To say that you are a tower of strength and endurance is a massive understatement! Your meticulous and unyielding and that is why your following is so very loyal. Not too many fit in your category because most either don’t care or run out of patience. We are so glad that you don’t! Jafro, you go guy! Looking forward to the next one big time!👍🏻
Jafro, you could take off a week or whatever time you need. It exhausted me just to watch it. It was easer for me to tear down that reel winder back in 2014. That was a terror, but I remember that wiring harness and all the hell it gave you! I look forward to that block rebuild after all that he’ll you went through with that. You got through more than anyone else I have ever seen! You inspire people and give hope to others. I’m proud of you and how much patience you have. I’ve been here since the Stone Age and I’ll follow you to the end! I respect you!
Ah yes, Jafro. I may not own or plan to own a 4G63 Engine, but the knowledge, foresight, cautionary tales, mistakes, insights, and general information dumping are all welcome. I feel more confident and more knowledgeable in how to go about tackling my projects in intelligent ways. Don't change a thing Jafro. Hope to meet you one day and go for a ride in eachothers projects.
Thanks for the shout out bud and all the help and pointers with my build as well. I see you used my harness in the video awesome. Really can’t wait to so see what what the Elantra will do now that it’s not going to have any wiring issues!!
@1:17:51 - damn that's satisfying! lol. Watching this WHOLE video was awesome. Even crazier that you edited ALL of this footage too! MAJOR props to you Jafro for editing this video on top of making the engine harness. Best DSM content on UA-cam! :D
I was just looking at materials to do this job on my modified FC. Came to UA-cam and thought it was making a recommendation based on my searches. Talk about good timing.
I recomend 4rcustoms, I get all my gxl wire there, all colors with all stripes! I'm in the middle of making my harness from scratch for a Mitsubishi pajero with a haltech elite, deutsch bulkhead connectors on the firewall pass thru, deutsch everywhere and module bits of harness.... I literally bought 6000+ feet of wire, fully concentric and braided sleeve covered.... I love doing wiring!
This is by far the biggest behavior modification this car is going to get. I can not wait to see some passes out of the little one now. Great work Jafro
Saw the title, channel, and length of video. Immediate like before even watching the video. Time to grab the popcorn! I know what I'll be watching for this evening in quarantine.
On a non-daily driver, making a harness is something I would in fact like to do. When one company contracts from another for an engine, electrical information in manuals becomes messy and almost useless. Jump over to a DSM car and a factory DSM manual, and it's utter perfection. There are even patterns for troubleshooting, and even really basic language of what stuff is and why it is used.
You are a legend! I love the in depth walk through of the process.. I have always wanted to rewire a entire engine harness but haven't had a chance yet..
I'll even go out to make this statement if I was ever in a position and I met someone like you I would make sure you had a garage that you'd be able to do anything you wanted in it just for the circumstance that you were able to do a video like this and educate people that's where I think this should go to thank you again
That wire stripe tool is ingenious. The harness turned out better than OEM, you took great care- with no piece rate or supervisor to worry about. This is another amazing video, thank you. I missed the chocolate music.
Home Depot Racing, baby! It did turn out rather well. I admit I ended this video at proof of concept stage. I have plenty of things I'm doing to the Hyundai that don't require a video and aren't directly related to the harness that this caused, but it did turn out REALLY well, and I'm still making it better. Thanks man!
I have worked on a few of these 1g harnesses, at 11:03 that connector is ether for the water temp switch on the thermostat housing it is for the A/C on a 1g dsm, or it is possibly for the the A/C pressure switch they both use a similar style connector. at 11:14 that round connector is for the A/C clutch 1g dsm. at 12:28 that is the rear defogger relay for a 1g dsm commonly deleted from the engine harness on dsms.
I'm glad you made this video so I didn't have to. The custom wiring I had to do on my Datsun was quite the project. Although there are companies that make custom harnesses and can easily replicate a stock harness, in my case and yours, there are several other circuits eliminated or added that you may not account for when ordering a custom harness. The price is well worth it either way. I wouldn't change the learning experience for anything and the knowledge gained in knowing what and where each circuit is and can fail is invaluable. Side effects of you new harness may include some changes to your tune since new, less resistant wire may carry a cleaner signal. I'm thinking I'm getting phantom knock due to a cleaner and shorter signal from the knock sensor. When I replaced my chassis harness with TXL wire, I found several circuits to be more sensitive due to 45 year newer and less corroded wiring technology. My engine harness is all Mil-spec tefzel wiring and allowed me to use lighter gauge wiring in many circuits. This was especially useful because, like you, I found that they don't make striped wire in larger gauges. Maybe some day I'll post a much more condensed version of your video about my own harness powering my 4G63 Datsun 510 #4G63510 :-)
i gotta say, i clicked on this having absolutely no idea who you or your project was and i feel like we just went on a cross country road trip together. Excellent video. I am blown away with your dedication and expertise. you sir have earned yourself a subscriber!
Wow, you could tell it was a ladybug. OMG, 4K is worth it. What I didn't know about ladybugs until I was making this video is that they eat spiders. I had an outbreak of them in my garage and at first I thought it was a problem. I haven't walked through a spiderweb in my garage now in over 4 months. They're gone. I'm grateful! Those little bastards ate every last one of them.
As a automotive electrical engineer I congratulate you on a great job. Really well done. Some tips from years of experience, None of which directly apply to what you have done, you have a done a great job and will have leant an unfathomable amount about how you vehicles connected that will assist you greatly, anyhow: - Cheap/off brand ratcheting crimp tools will let you down more than sturdy conventional crimping tools as they lack the "feel" that you get with conventional crimping tools when setting a good crimp force, Thus they tend to produce a lot more under crimped terminals when using wire sizes that don't fully fill the barrel of the crimp. - Fuel and vapor stable Raychem/heatshrink covering in good quality will cost nearly as much taping to assemble for sending the loom away to get covered with braiding $10/foot usd. The general procedure is make the loom but only tape with loops every 6 inches or so, test it in the vehicle then send it away for covering. This is a service performed by loom manufactures OR boat and marine rope manufactures. You can also customize the color of the braid. But to be honest split corrugated sleeving and tape is underrated. It has served the automotive industry for years with its cost effectiveness and serviceability. Even the aerospace industry uses tape and split sleeving. - If you want to do a one off and don't want to buy 100 rolls of cable you can source 25+ core cable that is all colored, strip the outer off this to get a vast array of colors. Never use numbered cable in an automotive environment unless absolutely necessary as eventually the numbers will come off from brake clean or chaffing. - heat guns can some times under cook those heat and solder connectors, good brand ones will withstand a high heat without splitting, cheap one won't. Never use those on tarnished wires, instead use the red/blue/yellow crimp terminals that have the glue and shrink (hella 8230s or other brand equivalent). the low melt solder in the solder ones tends to struggle on any wiring that's not 'bright and clean. - make it on a template board just in case you ever plan on doing it again. - Every one gets fooled by the same color wires transposed on one off builds, it's a "right of passage" like leaving the retaining ring off when assembling a garden hose fitting.
Boost Circuit??? Did I hear that right??? Are we putting a boost gauge in once again?? God this video was awesome, the only thing I think you should add to every video that you current don't; is the links to where you bought what tool etc. You should get some kick back from that as well. I know a lot of UA-camr's list where they bought they materials in the video description. I will be watching that over and over again to see what I missed the first time. I'd imagine you'll be making a new harness for the Colt as well...Ya know since you have spares :-) Glad to see this video, can't wait to see the next one!!!
The harness is already done on the Colt. That doesn't mean it's any better than the one that used to be on the Hyundai but... Yes. AND. That means it has all the connectors on it already. All of the cars have the connectors. The only bad ECU connectors were on the Hyundai. That means I can break them in half before I need to use the one with a "bad" pin 106. Some people accuse me of being an optimist. I'm leaving everyone in the dark about the boost circuit. I've got a trick up my sleeve if it works...
I was literally on the fence to build a new harness and this video appears. Needless to say, my mind has been changed...junkyards ahoy! Excellent as usual!
Yeah, it totally isn't for everybody! Or maybe not every car... You pay retail buying supplies. People who make harnesses professionally don't. If the car is available in a junkyard and you can get the part, AND you haven't changed a quarter of your sensors over stuff from other manufacturers, then why make your own? This is exactly why I made this video. I hit all 3 of those points with a 1992 4g63 swapped Elantra. If your thing isn't scarce, you can't beat the junkyard price.
"Anybody that is considering doing a wiring job like this...." me, finishing that sentence : just don't! :D Awesome job, but I would not have the patience to do it. Amazing !
I looked at the title and then the thumbnail and took a deep breath before clicking. You're a champ. I'm not going to question why on a Hyundai but you're a champ.
If you're new here, the car has an interesting story. There's a playlist. There's only 2 Elantras that have run a faster 1/4 mile time than this one and they're the same 1st generation model. So because you didn't ask, I didn't answer. Nobody ever saw me here. PS: Thank you for watching!
Same here Jafro, ive rewatched both the mini and the escargo builds since the lockdown. All you guys are awesome and inspirational. Your the reason ive almost got my evo2 back on the road. In the last 5% of fixes now
Guy don't make excuses you're a damn good mechanic and there's people out there that don't understand a lot of things and you just explain a whole lot me being educated in college about automotive it helps me out now having someone like you in the world because since then I've had traumatic brain injury and what you have done has re-engaged a lot of memories where I've lost education by the brain damage now I can reaccumulate my education that I lost through that thank you
I don't have to do a wiring harness, but your thorough, nature, and step-by-step explanation gave me a day that I did not have to take my OCD meds, much appreciated. 😁
Who would have thought I just spent an hour and a half watching a video on a wiring harness for a car and engine that I don't have! (probably everyone that knows how crazy I am) Thank you so much for your time and information, so many useful points for doing any engine harness that I actually took notes! Stay safe.
I've been working with wiring harness technical drawings and diagrams for the past 12 years. I know how hard a job like this can be. I admire your Work and immense effort. Congratulations. Marcelo from Brazil
Ur was the first video that dressed EVERYTHING I needed to know even the pins on and OFF / OUT of the harness !! Thank U , I’m a woman so of course it’s harder for me and I’m in my later 60’s so I still save money on fixing my own
And........... breathe!! In a former life you must have been a racing commentator :) Great job on the harness, and a brilliant voice over, thanks fella!!
i can't believe i watched a whole hour of this, but it was way better than I thought it would be. I'm a subaru tech and enjoy electrical work, so this was somehow right up my alley.
I made my own harness a while back and now I came across this. It's so funny to see someone go through the same issues I did but obviously some things you did were different and it was a relived nightmare watching you. I would think it would be great to sit down or even chat about harness building
I specifically bought the HP Academy wiring course so I can build a harness one day for my GVR4, but this will be a great, more concise, and more specific reference to compliment it!
GREAT job, James! Those guys really are awesome. I should have done the same, but it's more organic if I just do what I know how to do. It's a respect thing. It would have been really messed up to buy their course and expose any of it, but who am I kidding? I can't do what they do-the way they do it. I might have to make one for my galant as well, we'll see? I hope not.
Hi. I truly appreciate your KISS (keep it simple stupid) approach. If you can build what you need, get exactly what you want, and save money to boot, BUILD IT. Hoorah. I was a master technical instructor in the military and when I tell you your explanations are very good, and the little extras you sneak in are appropriate and appreciated, I think it's an informed opinion. But that's my opinion. My expertise was in digital equipment technology. I'm 68 and retired now and am trying to learn more about auto maintenance. Thanks for an excellent presentation. I enjoyed it and learned a lot. -Dave
Okay so officially I watched one hour and a half about a random guy who was suggested by UA-cam algorithm, making a wire harness for a model car that I don't have. Liked and subscribed and got the bell :), that's a really hard work that I hope I dont need to do with my Hyundai Accent 1997.
I can not convey to you how happy I am for you. Under the best conditions, a Mitsubishi electrical system can be iffy over time. I know how satisfied you are and that your car performance will finally be focused on tuning and upgrades. P.S. They do not call it "Painless" wiring harness' for nothing. lol Thanks for taking us on the journey. I can see myself doing this in the not to distant future.
I do have to say, when I was in high school I had a rough understanding of cars, they interested me but I never had a huge grasp of them or love for the hobby for that matter. I own a 1967 GMC 910, after watching cylinder head 200 series and especially the Elantra engine blue printing series (multiple times) I have grown a major understanding of engine building. Using the tech shown in all your videos Jafro, I was able to excel in the world of mechanics especially engine building. Watching you rewire your whole engine loom reminded me of my first and subsequent second (and far better) attempts of wiring. I am now in a career that deals with essentially "ECU's" but for major oil and gas facilities. I will continue to learn and earn more money at my day job which I hope to send some your way as I would not have the mechanical aptitude or technical skill levels I am. You Jafro have made a major impact on my life and these videos are greatly appreciated in the cold winter waste land of Canada!
My god you actually are insane lol. I admire your effort and congratulate you on your success, however i am also perplexed as to how you can work on and put up with 90s Mitsubishi and Mitsubishi based vehicles for any length of time. The mere shot of your foot well and under dash area was enough to trigger my PTSD, causing me to leap from my computer chair and sprint towards my mid 90s Nissan import just so i could sit in it and console myself. Jokes aside, i literally just finished a similar task on my Skyline. I had to reconfigure my existing RB25 engine harness to route and work on an RB26 based injection and sensor setup, delete unused hardware, as well as add in features like wide band o2, boost control, modern knock control and ECU monitored oil pressure and oil temperature control. Granted i didnt have to rewire my ecu connector but i basically had to redo everything else. I even went to the effort of utilising old and unused OEM power circuits and grounds for other components. I also went for an OEM look with inch Nitto loom tape, OE conduit and PVC sleeving for the branches. Im pretty happy with my results and i got to learn a lot about how the various circuits function. Also those "TinFmoon" connectors are actually Sumitomo MT 090 connectors. Found on most Japanese cars in the 90s. Also any of the connectors that have the brown/grey bum clips on them, (injectors) are JFC (Jet fuel control) connectors, which are pretty hard to come by.
There's UA-cam.......and then there's Jafro.

@Lassi Kinnunen same color?
There was a time we’re wiring wasn’t colored. Check out old Italian autos and such and you’ll see it’s all exactly the same color. I wonder if the same was true for rockets and such as they are kind of single use.

Your uploads are nothing short of stellar. You deserve to be in the YT automotive content creator Hall of Fame. Not only are your uploads informative and creative, but entertaining as well. One does not have to be specifically tied to JDM products to follow your work. As someone who has followed-subscribed for quite some time all I can say is thank-you for all the effort you put into all your work . You rock Jafro!
"Its on its sixth build and its third car MEOW"
Made my day! Salute to the Super Troopers.
Alright, I just watched an hour and twenty two minutes of you doing this wiring. On a vehicle I have absolutely no notion of every purchasing. I must say though, for the black wire being the only cause of the issue you had. PHENOMENAL work good sir!
Welcome To The Madness idk why but it’s good entertainment
I actually enjoy wiring. But this was on a whole new level. That wire marking tool is just genius. Thank you for this video it was truly great
no kidding, i really want one.
Hey we both uploaded DSM content today, DSM content overload for the people!
HECK YEAH! The most consequential imports ever built. I bet all kinds of DSMs are getting fixed right now while everyone's locked down. The only thing that interferes with their maintenance is their owners having a day job.
So I just happened upon this video, but figured I'd pass along some "knowledge" if anyone needed it down the road. There is a place in North Carolina called Miller Import Parts that dismantles DSM's and other cars. Found them when I needed a crossmember for one of my Nissans. Perhaps this will help either or you, or someone else, find parts if they ever need them.
@@TylerGotAYTAccount Ya I friended Stevie a few years back and got some hard to get parts from him, real good dude.
@@TylerGotAYTAccount lol i actually purchased a 1gb engine harness from miller import parts they are great to deal with
That wire striper is incredible.
This going have to be the sweetest 1hr I watch UA-cam, like button hit already.
Worth the wait, for sure. As someone who has completely re-wired my own car, converted from a carb to EFI, converted from mass air to speed density, and completely rewired from fuse box to cigarette lighter, I especially admired your attention to detail. It's a long and tedious job. Props to you for actually using the correct factory wire coloring, my junk is a mass of red and black wires! This is by far the best harness wiring project I've seen on the 'net. I'd love to see a before and after picture of some of your log traces to see the difference in noise in the different channels, especially the TPS, MAP and Battery voltage channels. I know my own logs cleaned up quite a bit when I put some attention to the grounds and signal wires. Great job!
That PVC marker holder/striping tool was genius, seriously. I'm a cheap bastard with a Honda, so I usually just get marked wire out of the newest/biggest Honda I can find in the junkyard. I'm also usually only replacing one or two sensors worth of wires that I think need to have the same exact color.
Uploading damn movies now! Nice! Who needs Netflix when we have Jafro?
Wires: The movie
Directed by Jafro
There is NOTHING more satisfying than finishing an engine loom or doing a full proper repair. Personally I prefer TESA high temp loom tape for the ends and corrugated tubing for the trunks. I heat shrink for abrasion if wires come out of the trunk at any point.... great job
I know what you mean about DSM wiring. I used to own an old 88 Dodge Conquest TSi widebody and had nothing but wiring issues with that car. Hats off to you sir for going through all this work 👍🏻
Your WIRE STRIPER is genius and yes I searched online...got distracted by all that stripping...then the other half got home and we got distracted...by the stripping...and that's my excuse for taking 18 months to see this to the end.
I'm so glad I watched this. To see the Joy at the end when it started was extremely satisfying.
Just pulling the old harness out made my head hurt. By the time he unpacked all the tools, wires, connector etc. I had a migraine! Just got done redoing the harness on my sons 4 wheeler and after I was finished I kicked myself in the ass for not just buying a new one, I couldn't imagine even attempting one of this size. Great video funny as hell and really an awesome job.
I'm about to do it again... That's the other downside. Once you've done it, you're less resistant to starting this job up and doing it again. Seriously, read down your bucket list. You'll find this item re-appears. I don't know why it does that? I thought I was finished?!
@@Jafromobile I agree you do become less resistant. I like to leap into the things I'm not completely comfortable with because of the experience and knowledge I usually gain (after alot of swearing). This however was something I definitely wouldn't want to tackle unless I knew that car inside and out which clearly you do. Great job I look forward to the next one.
Has no one ever thanked you for the time and effort you put in these videos?
Thank you, I appreciate you information you always provide. (:
I’m a woman so it’s harder for me to find what I’m looking for in my late 60’s u have done a great job addressing everything in ur video ty !! I’m Still trying to save money by doing my own van repairs
Wiring is like porn to me being an automation electronics engineer. Watching it done at this detail and with Jafro's easily comprehending explaination for as long a movie lasts... was the high point of the quarantine!
"Just buy a harness, if you can it is cheaper" Naw, now you know everything there is to know about your electrical system, what goes where, why it goes there. This is super valuable info, that can only be understood by making your own harness.
This is probably one of the best cable porn movies:
- Unnessasry chatty parts fastforwarded
- Good quality strippers and properly cut dongles
- Kinky harnesses/whips
- Money shot at 1:17:52
I just bought a 77 dodge truck and wanted to fix the mess the old owner has...and you answered my hours of searching for colored stripped wires ....thanks
I apologise now, I couldn’t help but smile when you SIGHED at the beginning, I think we’ve all been there at some point. Great content as ever, prefect isolation entertainment.
Watched it all, never fast forwarded and so grateful I didn't... Jafro seriously the best.. a true DSM God
I make the videos you have to watch at 1.0 playback speed. I sped it up for you. ;)
@@Jafromobile much appreciated!! Now for that engine build!
I’m as relieved as you are that your harness worked and going through all the struggles. You’re far more patient than I am. To say that you are a tower of strength and endurance is a massive understatement! Your meticulous and unyielding and that is why your following is so very loyal. Not too many fit in your category because most either don’t care or run out of patience. We are so glad that you don’t! Jafro, you go guy! Looking forward to the next one big time!👍🏻
I might take 1 day off? Maybe I earned it?
Jafro, you could take off a week or whatever time you need. It exhausted me just to watch it. It was easer for me to tear down that reel winder back in 2014. That was a terror, but I remember that wiring harness and all the hell
it gave you! I look forward to that block rebuild after all that he’ll you went through with that. You got through more than anyone else I have ever seen! You inspire people and give hope to others. I’m proud of you and how much patience you have. I’ve been here since the Stone Age and I’ll follow you to the end! I respect you!
Ah yes, Jafro. I may not own or plan to own a 4G63 Engine, but the knowledge, foresight, cautionary tales, mistakes, insights, and general information dumping are all welcome. I feel more confident and more knowledgeable in how to go about tackling my projects in intelligent ways. Don't change a thing Jafro. Hope to meet you one day and go for a ride in eachothers projects.
Love it Jaffro! Who needs Tiger King when you have the DSM Wiring King!!
Thanks for the shout out bud and all the help and pointers with my build as well. I see you used my harness in the video awesome. Really can’t wait to so see what what the Elantra will do now that it’s not going to have any wiring issues!!
@1:17:51 - damn that's satisfying! lol. Watching this WHOLE video was awesome. Even crazier that you edited ALL of this footage too! MAJOR props to you Jafro for editing this video on top of making the engine harness. Best DSM content on UA-cam! :D
I was just looking at materials to do this job on my modified FC. Came to UA-cam and thought it was making a recommendation based on my searches. Talk about good timing.
I get wiring questions all the time and I've never understood it? I'm like, "haven't you seen the Hyundai?..." Really this video was overdue!
I recomend 4rcustoms, I get all my gxl wire there, all colors with all stripes!
I'm in the middle of making my harness from scratch for a Mitsubishi pajero with a haltech elite, deutsch bulkhead connectors on the firewall pass thru, deutsch everywhere and module bits of harness.... I literally bought 6000+ feet of wire, fully concentric and braided sleeve covered.... I love doing wiring!
Evil Me seriously! How did he not find them when searching for wire??
This is by far the biggest behavior modification this car is going to get. I can not wait to see some passes out of the little one now. Great work Jafro
That Juicy Smolliette joke was on point.
10 minutes in and i think i found my new favorite auto build channel hahaha
Amazing! You strongly remind me of This old Tony.
I imagine this is how This Old Tony sounded in 6th grade
@0:30
I've been wanting a harness for my Escort for a few years now. I clicked this video and lucked out it was Jafro. lol.
Saw the title, channel, and length of video. Immediate like before even watching the video. Time to grab the popcorn! I know what I'll be watching for this evening in quarantine.
On a non-daily driver, making a harness is something I would in fact like to do. When one company contracts from another for an engine, electrical information in manuals becomes messy and almost useless. Jump over to a DSM car and a factory DSM manual, and it's utter perfection. There are even patterns for troubleshooting, and even really basic language of what stuff is and why it is used.
Mitsubishi wrote the best service manuals I've ever read. Even with the bad translations they're fantastic.
You are a legend! I love the in depth walk through of the process.. I have always wanted to rewire a entire engine harness but haven't had a chance yet..
I'll even go out to make this statement if I was ever in a position and I met someone like you I would make sure you had a garage that you'd be able to do anything you wanted in it just for the circumstance that you were able to do a video like this and educate people that's where I think this should go to thank you again
1:14:00 Stupid black wire looking like the other black wire.
That wire stripe tool is ingenious.
The harness turned out better than OEM, you took great care-
with no piece rate or supervisor to worry about.
This is another amazing video, thank you.
I missed the chocolate music.
Home Depot Racing, baby! It did turn out rather well. I admit I ended this video at proof of concept stage. I have plenty of things I'm doing to the Hyundai that don't require a video and aren't directly related to the harness that this caused, but it did turn out REALLY well, and I'm still making it better. Thanks man!
20 minutes in and my fingertips, neck, back and eyes already hurt from just watching this. Nope nope nope nope nope nope nope
yes yes yes lol
I already felt dizzy just watching this 🤣
This movie has everything, intro, trama, drama, plot and a happy end!! I'll started yesterday a similar project, I see everything is possible.
I have worked on a few of these 1g harnesses, at 11:03 that connector is ether for the water temp switch on the thermostat housing it is for the A/C on a 1g dsm, or it is possibly for the the A/C pressure switch they both use a similar style connector. at 11:14 that round connector is for the A/C clutch 1g dsm. at 12:28 that is the rear defogger relay for a 1g dsm commonly deleted from the engine harness on dsms.
It’s the prep work that gets you down the road to becoming your own assembly line.
I'm glad you made this video so I didn't have to. The custom wiring I had to do on my Datsun was quite the project. Although there are companies that make custom harnesses and can easily replicate a stock harness, in my case and yours, there are several other circuits eliminated or added that you may not account for when ordering a custom harness. The price is well worth it either way. I wouldn't change the learning experience for anything and the knowledge gained in knowing what and where each circuit is and can fail is invaluable.
Side effects of you new harness may include some changes to your tune since new, less resistant wire may carry a cleaner signal. I'm thinking I'm getting phantom knock due to a cleaner and shorter signal from the knock sensor. When I replaced my chassis harness with TXL wire, I found several circuits to be more sensitive due to 45 year newer and less corroded wiring technology. My engine harness is all Mil-spec tefzel wiring and allowed me to use lighter gauge wiring in many circuits. This was especially useful because, like you, I found that they don't make striped wire in larger gauges.
Maybe some day I'll post a much more condensed version of your video about my own harness powering my 4G63 Datsun 510 #4G63510 :-)
i gotta say, i clicked on this having absolutely no idea who you or your project was and i feel like we just went on a cross country road trip together. Excellent video. I am blown away with your dedication and expertise. you sir have earned yourself a subscriber!
36:05 That poor ladybug is like WTF have I stumbled into????
Wow, you could tell it was a ladybug. OMG, 4K is worth it. What I didn't know about ladybugs until I was making this video is that they eat spiders. I had an outbreak of them in my garage and at first I thought it was a problem. I haven't walked through a spiderweb in my garage now in over 4 months. They're gone. I'm grateful! Those little bastards ate every last one of them.
@@Jafromobile I had no idea. But I do know you can order boxes of live ladybugs on Amazon, so I'm about to and release them in my garage.
Don't know why I'm watching this at 3am but I enjoyed it, good stuff!
Hour and a half of Jafro? I think I can stretch it out for another month or two of quarantine.
Also, caught the predator reference at 1:20. Nice.
Great shout on the predator reference lol. I had skipped that somehow. brilliant!
As a automotive electrical engineer I congratulate you on a great job. Really well done.
Some tips from years of experience, None of which directly apply to what you have done, you have a done a great job and will have leant an unfathomable amount about how you vehicles connected that will assist you greatly, anyhow:
- Cheap/off brand ratcheting crimp tools will let you down more than sturdy conventional crimping tools as they lack the "feel" that you get with conventional crimping tools when setting a good crimp force, Thus they tend to produce a lot more under crimped terminals when using wire sizes that don't fully fill the barrel of the crimp.
- Fuel and vapor stable Raychem/heatshrink covering in good quality will cost nearly as much taping to assemble for sending the loom away to get covered with braiding $10/foot usd. The general procedure is make the loom but only tape with loops every 6 inches or so, test it in the vehicle then send it away for covering. This is a service performed by loom manufactures OR boat and marine rope manufactures. You can also customize the color of the braid. But to be honest split corrugated sleeving and tape is underrated. It has served the automotive industry for years with its cost effectiveness and serviceability. Even the aerospace industry uses tape and split sleeving.
- If you want to do a one off and don't want to buy 100 rolls of cable you can source 25+ core cable that is all colored, strip the outer off this to get a vast array of colors. Never use numbered cable in an automotive environment unless absolutely necessary as eventually the numbers will come off from brake clean or chaffing.
- heat guns can some times under cook those heat and solder connectors, good brand ones will withstand a high heat without splitting, cheap one won't. Never use those on tarnished wires, instead use the red/blue/yellow crimp terminals that have the glue and shrink (hella 8230s or other brand equivalent). the low melt solder in the solder ones tends to struggle on any wiring that's not 'bright and clean.
- make it on a template board just in case you ever plan on doing it again.
- Every one gets fooled by the same color wires transposed on one off builds, it's a "right of passage" like leaving the retaining ring off when assembling a garden hose fitting.
"probably enough to do 3 or 4 cars" good thing you own three or four DSMs
Man, I gotta a major headache watching you rewiring your car... Power to you!!!! Great work!!!
Boost Circuit??? Did I hear that right??? Are we putting a boost gauge in once again?? God this video was awesome, the only thing I think you should add to every video that you current don't; is the links to where you bought what tool etc. You should get some kick back from that as well. I know a lot of UA-camr's list where they bought they materials in the video description. I will be watching that over and over again to see what I missed the first time. I'd imagine you'll be making a new harness for the Colt as well...Ya know since you have spares :-) Glad to see this video, can't wait to see the next one!!!
The harness is already done on the Colt. That doesn't mean it's any better than the one that used to be on the Hyundai but... Yes. AND. That means it has all the connectors on it already. All of the cars have the connectors. The only bad ECU connectors were on the Hyundai. That means I can break them in half before I need to use the one with a "bad" pin 106. Some people accuse me of being an optimist.
I'm leaving everyone in the dark about the boost circuit. I've got a trick up my sleeve if it works...
I was literally on the fence to build a new harness and this video appears. Needless to say, my mind has been changed...junkyards ahoy! Excellent as usual!
Yeah, it totally isn't for everybody! Or maybe not every car... You pay retail buying supplies. People who make harnesses professionally don't. If the car is available in a junkyard and you can get the part, AND you haven't changed a quarter of your sensors over stuff from other manufacturers, then why make your own? This is exactly why I made this video. I hit all 3 of those points with a 1992 4g63 swapped Elantra. If your thing isn't scarce, you can't beat the junkyard price.
"Anybody that is considering doing a wiring job like this...."
me, finishing that sentence : just don't!
:D
Awesome job, but I would not have the patience to do it. Amazing !
I looked at the title and then the thumbnail and took a deep breath before clicking. You're a champ. I'm not going to question why on a Hyundai but you're a champ.
If you're new here, the car has an interesting story. There's a playlist. There's only 2 Elantras that have run a faster 1/4 mile time than this one and they're the same 1st generation model. So because you didn't ask, I didn't answer. Nobody ever saw me here. PS: Thank you for watching!
That is exactly what my face looks like when looking at a wiring diagram
Over an hour of Jafro. Best day on youtube since BOM had a new episode
I love those guys! They're the best thing that ever happened to the Austin Mini and UA-cam. I'm enjoying the Escargot as much as Binky, really.
Same here Jafro, ive rewatched both the mini and the escargo builds since the lockdown. All you guys are awesome and inspirational. Your the reason ive almost got my evo2 back on the road. In the last 5% of fixes now
Guinness, ribs, chicken all ready. Now to slip into a chair and watch Jafro premiere.
Realised I didn't like this video when I first watched it, so I came back, watched it again and have it a like!
Felicidades un abrazo desde chile , sigue con su mision
Jafro es un Maestro. Gracias a el pude meterme mucha mano al viejo Hyundai Elantra 1.6 de mi viejo y a mi Eclipse. Saludos compatriota
Saludos amigo
dam. the car is too low and your not short at all, I hope this car deserves all this big work. love your skills good job
Loved the dry humor in this one, laughed a few times at your jokes 😄
The data log at the track joke was funny.
Guy don't make excuses you're a damn good mechanic and there's people out there that don't understand a lot of things and you just explain a whole lot me being educated in college about automotive it helps me out now having someone like you in the world because since then I've had traumatic brain injury and what you have done has re-engaged a lot of memories where I've lost education by the brain damage now I can reaccumulate my education that I lost through that thank you
"sixth build in it's third car meow"
Did he say meow
Yes he did
I'm sorry meow, but I'm gonna have to give you a ticket!
Do i look like a cat to you?
Am I jumpin' around all nimbly bimbly from tree to tree?
Do you see me eating mice?
I don't have to do a wiring harness, but your thorough, nature, and step-by-step explanation gave me a day that I did not have to take my OCD meds, much appreciated. 😁
He saw my comment about last video being literally one minute and was like..i see your comment its length you want.... 90 MINUTES IT IS!!!!!!!
I did... I saw it... I was all like, "be careful what you ask for..." ;)
🤣🤣🤣🤣
Once I buy my house and build my shop I'll be putting together that wire spool set up.... Genius!
@ that is true but I do car stereo stuff really often so for me spools of wire would be really handy
Who would have thought I just spent an hour and a half watching a video on a wiring harness for a car and engine that I don't have! (probably everyone that knows how crazy I am) Thank you so much for your time and information, so many useful points for doing any engine harness that I actually took notes! Stay safe.
"It's like a fart in a spacesuit" I've gotta find a way to work that into one of my zoom calls...
loved that analogy
I've been working with wiring harness technical drawings and diagrams for the past 12 years. I know how hard a job like this can be. I admire your Work and immense effort. Congratulations.
Marcelo from Brazil
aww dude a squeaky shoe is the worst. you sound like a cartoon character everywhere you go
Clown shoes IRL.
Might be time for some new gasket material?
Great video,Jafro.I especially liked the emphasis on the pink wire for the ladies. Gotta keep them happy! Be safe.
Great video. The electrical side of things always appeals to me more than mechanical. It's the satisfaction of finding the fault and fixing
Ur was the first video that dressed EVERYTHING I needed to know even the pins on and OFF / OUT of the harness !! Thank U , I’m a woman so of course it’s harder for me and I’m in my later 60’s so I still save money on fixing my own
And........... breathe!!
In a former life you must have been a racing commentator :)
Great job on the harness, and a brilliant voice over, thanks fella!!
i can't believe i watched a whole hour of this, but it was way better than I thought it would be. I'm a subaru tech and enjoy electrical work, so this was somehow right up my alley.
I made my own harness a while back and now I came across this. It's so funny to see someone go through the same issues I did but obviously some things you did were different and it was a relived nightmare watching you. I would think it would be great to sit down or even chat about harness building
I specifically bought the HP Academy wiring course so I can build a harness one day for my GVR4, but this will be a great, more concise, and more specific reference to compliment it!
GREAT job, James! Those guys really are awesome. I should have done the same, but it's more organic if I just do what I know how to do. It's a respect thing. It would have been really messed up to buy their course and expose any of it, but who am I kidding? I can't do what they do-the way they do it. I might have to make one for my galant as well, we'll see? I hope not.
Hi.
I truly appreciate your KISS (keep it simple stupid) approach. If you can build what you need, get exactly what you want, and save money to boot, BUILD IT. Hoorah. I was a master technical instructor in the military and when I tell you your explanations are very good, and the little extras you sneak in are appropriate and appreciated, I think it's an informed opinion. But that's my opinion.
My expertise was in digital equipment technology. I'm 68 and retired now and am trying to learn more about auto maintenance. Thanks for an excellent presentation. I enjoyed it and learned a lot.
-Dave
Okay so officially I watched one hour and a half about a random guy who was suggested by UA-cam algorithm, making a wire harness for a model car that I don't have. Liked and subscribed and got the bell :), that's a really hard work that I hope I dont need to do with my Hyundai Accent 1997.
Okay Jafro, one year later, I have to do this on my car... I don't think you will ever read this but thanks haha
I can not convey to you how happy I am for you. Under the best conditions, a Mitsubishi electrical system can be iffy over time. I know how satisfied you are and that your car performance will finally be focused on tuning and upgrades.
P.S. They do not call it "Painless" wiring harness' for nothing. lol Thanks for taking us on the journey. I can see myself doing this in the not to distant future.
I do have to say, when I was in high school I had a rough understanding of cars, they interested me but I never had a huge grasp of them or love for the hobby for that matter. I own a 1967 GMC 910, after watching cylinder head 200 series and especially the Elantra engine blue printing series (multiple times) I have grown a major understanding of engine building. Using the tech shown in all your videos Jafro, I was able to excel in the world of mechanics especially engine building. Watching you rewire your whole engine loom reminded me of my first and subsequent second (and far better) attempts of wiring. I am now in a career that deals with essentially "ECU's" but for major oil and gas facilities. I will continue to learn and earn more money at my day job which I hope to send some your way as I would not have the mechanical aptitude or technical skill levels I am. You Jafro have made a major impact on my life and these videos are greatly appreciated in the cold winter waste land of Canada!
From Henrico va., you are a genius , I have always wanted to make my own harness for my 90 tsi. Well done sir
Thanks for recapping and talking about what tools were actually useful
My god you actually are insane lol. I admire your effort and congratulate you on your success, however i am also perplexed as to how you can work on and put up with 90s Mitsubishi and Mitsubishi based vehicles for any length of time. The mere shot of your foot well and under dash area was enough to trigger my PTSD, causing me to leap from my computer chair and sprint towards my mid 90s Nissan import just so i could sit in it and console myself.
Jokes aside, i literally just finished a similar task on my Skyline. I had to reconfigure my existing RB25 engine harness to route and work on an RB26 based injection and sensor setup, delete unused hardware, as well as add in features like wide band o2, boost control, modern knock control and ECU monitored oil pressure and oil temperature control. Granted i didnt have to rewire my ecu connector but i basically had to redo everything else. I even went to the effort of utilising old and unused OEM power circuits and grounds for other components. I also went for an OEM look with inch Nitto loom tape, OE conduit and PVC sleeving for the branches. Im pretty happy with my results and i got to learn a lot about how the various circuits function.
Also those "TinFmoon" connectors are actually Sumitomo MT 090 connectors. Found on most Japanese cars in the 90s. Also any of the connectors that have the brown/grey bum clips on them, (injectors) are JFC (Jet fuel control) connectors, which are pretty hard to come by.
I was an hour in before I realized with was a 1.5hr long video, awesome work!
