I was always afraid to do an LS swap due to the wiring. I’m straight up old skool. Carb tune, timing, and go lol! Thank you for making this video! I’m thinking I see an LS swap in my future.
It's easier than you'd think. Just tedious lol
@@SniderTron3000did u use oem harness stand alone or buy a harness?
@@Brandon_obs_ls I used a $100 ebay harness
Buying an ls swap harness premade for your vehicle is a good idea when u have money to blow but the real lesson and challenge is when u do a stand alone is hard at furst but when u label and get an idea how every thing goes thats a huge gain in knowledge and satisfaction knowing.how everything is wired up u can pretty much do a stand alone for any vehicle thats the benefit of actually taking your time and studying the harness schematics after that it all comes together like a puzzle.
Pull the clock add oil pressure. Kool build.
I concur
LS wiring gets easier with time
Becuz we are Ls swapping everyday, right?😂
@@voltaoltav4686 if you've got a shop, absolutely!
would an 07 Tahoe wire harness have all the same connecters as an 07 suburban .. im replacing my ecm wiring because of a crank no start on my suburban LTZ . i lost all power while driving then my dash wouldn't light up after turning the key . after replacing ecm dash lit up and relays started clicking , then crank no start.
Thanks for this... In the middle of dropping an ls1 in my 67 camaro and was trying to figure out what to power that red ecm cable with 👍
You're killing it. I've thought about LS swapping my 97 camaro if I can get the funds together
Just go little by little. It can be done really cheap if you take your time and look for deals.
Same but prefer a ws6 a 5.3 swap with trans maybe a th400 or 4l80
I put a 4.8L in my 95' and i have a th400 i traded tires for.... really not looking forward to the harness build and im on a tight budget so buying a harness is outta the question lol. I built a tube front end and moved the engine forward 1" which gave so much room for trans bolts in the 4th gen fbody so windowing blocks isnt gonna be too bad for an over night swap lol
Good seeing ole Papatron again. Since your shop got done haven't seen much of him.
He's been busy with stuff at his place and battling a chest cold for like months that has been fucking with him. But we still go over to each others places pretty much every other day, a lot of it just doesn't make it into videos lol
I thought I remembered you saying he was sick as hell.... now that you mention that.
Well glad hes feeling better then.
Keep on KEEPING ON !! THANKS!!
Dig that new intro style! Good to see pops, too!
I just found this channel a few ago and subscribed as you guys need the help that are trying to make it easy for the next guy and since gm spit a few million of them now, find them at wrecking yards for affordable prices. Halfass Kustoms just separates the wires into catagories and uses the stock to LS conversion easy. If its cheap and easy, clean and no fussing, I lean that way. He explained it over the phone to DD Speedshop and he was able to do it quick and easy so moved on and while engine was out on the next swap had that bunch of wires sorted in a big hurry and running in just no time so money saved is more money for project. The system you have is really good for the kid who is in the learning to shave category. Plus its pretty but that is what the looms are for. I give a like cause your honest and straightforward
I don't see obd port under hood being a negative. I think it's cool. Everyone knows it's a custom car when they look under the hood. It would be cool to have to pop the hood on that particular ride to plug in.
I have been searching for this exact video wanting to ls swap my e30
When you have to crank an engine over to build oil pressure take the spark plugs out of it it'll buzz over fast enough with them out it won't hurt anything and it'll build oil pressure quick cranking on it with the plugs in you are gonna wipe out a flat tappet Cam I know the ls is a roller just letting you know takes 5 minutes to pop the plugs
Quality tech tip 👌
Thanks man keep up the good work, do a BBC build
I would love to. I found a Cutlass with a 454 in it on Marketplace the other day for stupid cheap but the guy never messaged me back
@@SniderTron3000 wow that would be the one to do man try again
Cant wait to hear this camaro running
looks Gud ! I want to hear that exhaust
I work at a hot rod shop and BP harness is the best way to go. PSI harness aren’t built as well and don’t look as well.
Link? I've never heard of BP. I've only used PSI once and it was pretty nice

@@vl639 hey bud great link thanx for sharing!! It looks like great prices too.
Great video. You helped me out. I was trying to figure out how to get power into the car and u answered it. Thanks
I love it with Wu-Tang playing in the background I hear your Clan brother!!! WTF
shop has great taste in music too!
Title is LS Swap Wiring, starts video with axle and exhaust work... :D
If you cut the numb off your black and decker drill that is in the middle by the battery prongs you can use a portable cable 20v battery in it I did it and it lasts for ever such a better battery
I would remove or replace those fuse link on the wires down by the starter. They gave me a hell of a time when i was 17. Lol i use to have nightmares. I changed so many batteries and alternators until i found out about these bastards. My uncles got a good laugh😂. They knew the whole time😡 lesson learned 😆
Those fuckers got me today. I spent an hour chasing down where I lost power and then replacing a bunchnof them lol
Howell engineering does a harness with pcm and uses stock gauges old school and a regular key switch wish it was cheaper
Classic Camero, LS & Wu Tang
🤙🤙💯
Hell ya for sure ls swapping my 95 2door yukon now wasn't sure before cause i want instrument cluster to work didn't know the harness made it that easy
The cluster wiring is doable. Theres a lot of forum write ups that get pretty detailed on all of it
Ima pussy when it comes to wiring and picky ass hell i wanna 6.0 and 4l80 swap it at same time its just alot to do and cant find much info on the 4x4s i got the doner truck just need time and money
Awesome video I got a 1985 C10 I'm gonna do a LS swap! Thanks for the info
5:13 the computer sends a low voltage signal for the fans. You need relays to make this work!
Yes.
that pcm looks offley familiar dont forget to turn off vats on it
🤘🤘🤘
I guess the question is the key crap to get power to the pcm theft system
First thing i see is someone beating in a bearing cap with a claw hammer lmao. This is a video for me lol
Awesome build.
Right on time for my lunch break. Thank you
5:47 I was waiting for the clock to be one of the big gauges like a 84 Bonneville.
You deserve more views
Im getting ready to swap a 5.3 / 2003 trailblazer into my 1990 k5 blazer.
I have a complete donor truck trans engine computer harness... but ill admit im very intimidated bu the wiring.
I love wiring , says no one ever .
I don't mind wiring, I just hate troubleshooting wiring and tracing them down
Looks alot more daunting than it actually is. IMO the only downfall to having the obd2 port in the engine bay is tuning. Once that car is done and rolling, James Brown will be getting the love and attention he deserves.
Yeah, but if you have an MPVI2, I believe those are wireless, so its only inconvenient for poor folk like me haha
Man Every time I watch you LS swap makes it easier and easier to sell my bike and start LS swapping my falcon
DOOT!
@@SniderTron3000 DOOT?
Dootdoot= do it lol
The only thing I didn't show you is everything lmfao
What color is the starter wire coming from the connector on the fire wall awesome build bro TIA
Hell yeah brother. Great job
Can you send me info on how to use stock harness for 5.3
I just don't understand what you do with all the original wires coming out of firewall.
Nice. Looking really good Buddy
Big help
What’s the name of harness I’m running a turbo 350 on my Jeep the pci harness well work
Hell yeah brotha car is coming together nice bro cant want to see it rip want to help me on my fox yet hahahahaha
Sweet nectar. Cant wait till the burnouts happen
She's looking good.
I’m swapping. An 80 Firebird that had no engine or trans what wires from the cars bulkhead did you use (other than gauges) and where did you hook them up? Starting powering up the cabin etc. I’ll pay for info
Hell yeah brother!!!!!!
I’m thinking about an 5.3 LM7 swap on my 97 Chevy OBS truck. What do I do with the ECU do I just reprogram the vin of my truck to the ECU?
Literally doing the same swap. Still trying to figure out everything that needs to be done
hi there i have the same wire harness but i dont have any instruction with it i have a efi tank how can i build a relay off this harness
Hey I was wondering did you use any of the wiring from the stock engine harness for your LS swap because Or did you just use the psi standalone harness
Hey I have a 1988 k5 blazer and I’m getting ready to ls swap it I have the harness already. But my question is do I remove the stock harness?
Any comments on dropping 6l LS into 97 GMC Sierra. Wiring concerns?
Great video keep up the great work
I really want to LS swap a Ford Ranger
They're pretty rad
hello how are you plz i have hummer h3 2006 v5 3.5 l with E40 ECM if i find v8 gn4 with E67 Ecm and harness i can put it on my h3 and work properly all gauges and ABS and traction control? and transmission sure i wanna make changes in the 4l60 to v8 ...
I think i just blew my 5.7 in my 93 1500 2wd stepside. I'm 50 yo, I dont know if I can do a swap.
If you can do a sbc swap and wire up an MSD box, you can do an LS swap. But, buying a swap harness makes it a lot easier
Stupid question ik this vid is a year old, but I am LS swapping a third gen Camaro that also had a Speedo cable and I’m running a 700R4 so can I just use the cable on the 700R4 like my speedo will work completely fine? Just wondering cuz I’m new to this as this is my first motor swap and obviously my first LS swap
Yeah, you should be able to. Especially if the car had a 700r4 to begin with
Great job and great video 👍👍
Impressive work Sir. When are you going to put heat in your garage?
At this point, probably next winter haha
I love the beginning beat at the beginning. What is it called?
Putting a lq4, green/blue pcm ,DBC in a c10 from an 04 gmc savanna . Can I use a red/blue standalone harness for DBC and just can the red connector on harness to green? It seems like all the green/blue standalone harnesses are dbw not DBC . Thanks to anyone who can offer any assistance
Easy when you but a premade harness yes. Lol try it from scratch not so easy then.
I have no desire to do that when the $270 ebay harnesses work so well lol
Where did you get the wiring harness? And how much
Nice video keepem coming
@SniderTron3000 where do you get a swap harness?
This is just an ebay harness
What wire powered your fuel pump from that harness?
Dude. How would I make a 98 dash with controls work on my 90 tbi harness?
whats the white long thing under the car
Miss your content! ✌
❤❤❤
Wait I’m new to ls swap so u can use a turbo 350 transmission with a ls
Yep! Th350, th400, powerglide, etc
Where I can get the harness swap book
to wire the alternator, what wire do you use? or did you use all 3 wires into one terminal?
That’s what I want to know
What did u use to mate the 350 turbo with the ls and I’m doing a turbo 350 the wiring harness I’m looking at has a 4l60 harness with it could I just leave it disconnected?
It bolts right up, just buy a flexplate for like a 2003 GMC Savannah van with a 6.0 and 4l80e. But that has a bolt pattern for a th400 converter, not a th350. Just need a converter with the wide pattern
So UA-cam algorithm what you trying to tell me with all these ls swap vids. Trying make me drop one in my K5 or K10.
That has got to be the easiest I have ever seen a u joint go in 😂
They usually go in easy, its getting them out sometimes that is a pain in the ass. At least for me haha
Did you learn to weld on you’re own ?
Yessir
just gotta have deep pockets lol
The manual that you referred to in the video what is that???
Its the one that came with the wiring harness
@@SniderTron3000 what harness did you use? Cut down factory or Holley ?
How similar is a LH2 to an LS in wiring?
Interested in building SVO mustang to LS1 swap.
How complicated will the wiring be ??
It would be no different. Unless your trying to make the ford gauges run off the LS harness
Tried tuning my ecu, but my obd port only lets me read the codes. Some people tell me add another obd port but idk what to do can you give me an idea ????
I have no idea on that one. Never dealt with that issue.
how much do you charge to rework harnesses??
Hey I want to do this c4 corvette what motor should I go with
Whatever you can get. My buddy with the blue blazer went 9.90's with a stock bottom 4.8/cam/smallish turbo. I like 5.3's, they're cheap and still make good power
Hey snider me again, so on the starter I put both red ring terminals from stand alone harness along with battery positive on the starter and that’s it? (Purple boy is hooked up to ignition already) got confused stand-alone has one black one red sleeve on the two terminals
I wonder if those are supposed to go right to the battery? But I have seen positive cable with black heat shrink on them before
@@SniderTron3000 thanks bro I was confused I kinda torched a starter but will attempt again with the way u explained it hopefully I won’t blow I’ll be able to show my 98 camaro ls swap 6.0
Good shit, man. Good luck with it 🤙🤙
I need yo help yo location got a 87 caprice need that 5.3 put n
I'm in Michigan. If you're south more check out Swaps Performance on YT, he's a good dude
Where harness did you get
Ebay, but I would recommend a PSI Conversions harness
Got any feedback on that Vulcan welding hood ? Considering buying one
Solid 8.4/10. I like it a lot. Very comfortable.
SniderTron 3000 thanks man. 🤘🏻 probably going to pick one up soon the.
i also have a prime weld tig how do you like yours
I like it. I just need to pracrice aluminum more lol
my intake is drive by cable but i have ev6 injectors and any harness i can dind has ev1 connections, do i have to swith over to ev1 injectors?
You can just order adaptors to go from ev1 to ev6. They're like $20-30
@@SniderTron3000thanks i did that, one other thing if you dont mind helping, can i use my cables from my 97 or do i need different cables?
Hey I’m ls swapping my 03 s10 what pan should I use to not have to cut the k member?
You'd be better off looking on the forums, I haven't done any research on it yet
Question for anyone who can answer I got a 4.3 Silverado and 5.3 Tahoe can I swap the engine/ecm/wiring from the Tahoe to the Silverado
As in will the computer allow the engine to run without any tuning or anything I have the same trans as the Tahoe
Where did you get that print out to your wiring diagram?
Came with the harness
@SniderTron 3000 I have question do you need a steering column for engine to start that's what this guy told me if I do ls swap I'm going to need the engine key because of a chip
Nope, that guys a chump. If you're using a stock computer you'll have to turn Vehicle Anti Theft System off in the tune, but thats all. You can run these engines with 4 basic power wires
@@SniderTron3000 Thanks I did see alot of videos where people dont mention about the key and chip
I'm thinking about putting a 5.3 truck engine I'm my 96 Camaro is painless performance a good company?
Painless is good, but depends on what you're trying to do. If you just want an LS engine harness, PSI Conversions is probably the best in the game
@@SniderTron3000 I'm putting my 5.3 truck engine in a going to put a ls6 intake and put a ls3 camaro water pump and maybe a turbo in the future
@@SniderTron3000 I have another question would an ls6 intake work on a gen 3 5.3
Scratching my head... if there’s two wires going inside for tach and such why not throw the obd wires inside all together
Honestly, just inconvenience. The dash still has a huge air boxes and shit behind it and I just didn't want to deal with trying to either fish the harness through there to make it all fit right or gut that all out of there and then down the road he wants to put it all back in there. Idk, laziness I guess lol
Any news on Goldie?
Got the new cam/springs/hardened pushrods. Turbo manifold and S475 are mocked up on the engine stand just need to make a crossover. I'll go more in depth in the next video with an update on Ol Girl
