Today, we delve into the VERY technical details surrounding the building of my flooded McLaren P1's wiring harness. We had to make it from scratch so there's a lot to talk about. Wish us luck!
If anyone is going to have wiring issues with their McLaren, this guy's going to be an expert. He's probably going to make a living on solving McLaren wiring problems for life.
Especially since he has solid gold: all the actual wiring diagrams…
I would never want to touch a wiring harness again after something like this. I am wondering that it would be cheaper to just buy a new harness at this point.
@@stazang I think it is overall, from what I understood he said he wasn't going to do it because it would take around a year for it to come and by that point with the little money he would save by having them do it, it wouldn't make a difference. Unless I am wrong on the reason for it
@@stazang the wait time is prohibitive.
It probably wouldn't be much cheaper if any from McLaren also
Let me say this. Adam is the biggest geek on earth. I say that in the most positive way possible. What he has done is doing with that wiring harness is beyond impossible. To be able to look at the ruined one and then think he can make his own is unreal. I wish my mind worked like his. To me this is by far the most amazing accomplishment of this whole project. Adam your are insane. It’s not just the fact you can make one. It’s the time and how tedious it must be not to mention what would happen if you make one little error during it. Adam my man you deserve the first drive of this car once it’s finally done.
It's not impossible cos he's doing it, and he's not making one from scratch, what he's doing is putting 2 wiring harness to work with a third system for which one is very similar to the third. He's very intelligent and a professional but not an impossible task. The greatest difficulty here is figuring what to move where, else anyone can take on the challenge. I've seen people build custom wiring harness to add or modify features on a car, this is no different.
@@kelvinkeme9397 I know what he is doing I’m able to hear as well thanks. I’m unfortunately not like you clearly someone so impressive as yourself that you see this as nothing. What an impressive person you are I’m sure your parents are proud. I’ll stand by what I said what he is accomplishing is amazing even if you and your clearly brilliant mind doesn’t think so wow
Adam is a wiring genius
@@mauraece I agree tho this Kevin guy that commented seems to think what Adam is doing is easy and no big deal. So maybe you and I just aren’t that smart lol.
I never said it was easy or I'm not impressed, you said it was impossible, but he's actually doing it so it's not impossible. My 2nd point was he's not building one from scratch, like you said. He's modifying 2 systems to make a custom system. Who wouldn't be impressed? I did say he was intelligent and a professional, pls comprehend what I said. I'm not hating.
Adam is the MVP of this project. This is crazy
I would say so!
As an avionics technician, I used to wire military helicopters. Kudos to you guys taking this on.
The *confidence* it takes to take on such a project ! A complete wiring harness from scratch for an entire Supercar that is supposed to become the fastest McLaren ever.
That takes a lot of courage, even if you have the skills and the experience. I admire him for that.
100%...now add in supercar lunatic engineers and you've got a dog's breakfast from 3 diff dogs who ate diff things at diff times.
After so many projects and with his connections and resources (well earned) there's no reason why he shouldn't finish this one.
I.e. he's on a completely different level from 99pct of us.
Respect to the loom guy that’s a massive undertaking
As a guy who has spent most of my professional life building, and wiring, machines, I can appreciate the magnitude of this entirely! Combining, and cleaning up all the grounding is probably one of the smartest things you can do to insure reliability down the road. I've had nightmares with CAN systems because of grounding, and poor connector continuity (either from construction or corrosion over time). If a signal gets dropped, or lost due to a resistance change, the node just disappears, and won't come back until the system is rebooted... That's part of that mystery magic you see in a lot of these exotics where they shut off the car after an issue, disconnect the battery, wait, then it suddenly works... anyway, those Amphenol connectors are killer; great choice! Fantastic job guys!
Say Amphenol three times really fast 😂
Once you understand the amount of work that goes into even a simple body harness swap, this looks like even more immense project! Now you have to graft multiple chassis models into one working harness with no communication issues or faults, not to mention the coding involved. Mind blowing Man! When this car is done it’ll stand tall next to any other legendary McLaren IMHO, including the famed F1. This will be a 1/1 in history and I’m here wide eyed to see it! 😮
Whatever Adam is being paid for this work isn't enough. He's definitely earning every pretty.
I used to build electrical harnesses for an aerospace/defense contractor, it was quite stressful at times, but nothing was quite as satisfying as doing the final continuity test and every contact on every connector got that beautiful beep lol
We use a CIRRIS tester at my work, so when he mentioned testing every pin by hand that was my first thought. But then I remembered that you'd have to make test cables with corresponding connectors for the entire harness, plus you'd have to create the test program, which would essentially mean doing this whole project twice.
@@mrflippant Yeah we had quite a few of the same harnesses that got built quite frequently, so we used the CIRRIS for those, but we also did a lot of one-offs, so those all got hand tested since making the test harnesses and programs was no small feat in itself.
Would be a good idea to seal the bulkhead connectors to ensure the surface will not allow water ingression. These bulk head connectors will allow to ring out the harness in sections too. Do a full continuity test per pin.
Ain't you supposed to load test?
I would love to watch McLaren Engineers reacting to this video! 😂 I am sure they would have colorful commentary on how bonkers a project this is! Good luck, gents!
there is noway they do harnessing on site, they just buy it from a sub contractor in Asia or something like that.
I bet McClaren would want to hire you for their wiring improvements since you are making your harness modular!! REALLY SMART!! Thank you for taking us along on your journey!! May God overwhelm you, your staff and family with blessings!!!!
I am working as process engineer in cable harness manufacturing, and when I see this challenge, I think "WÆÆH". Reverse engineering and manufacturing is 3 times more difficult than manufacturing from drawings and this a pretty large cable tree, which is realistically hundreds of engineering hours + sourcing + manufacture. I'm impressed, boys! This is a serious one!
How much of the process once design is finalized is automated? Because the millions of new cars built every year you have to have a way to pump them out enmasse to keep up with demand
@@17semprfi A lot less than you might think. Cutting, labeling and crimping individual wires is largely automated, but for mounting the harness there's a lot of elbow grease and skillful handwork involved. Also, only one side can be crimped automatically, since the other end needs to be cut to exact length and crimped during mounting.
Adam is an absolute machine. He is the unsung hero of this whole project for sure
I am a wiring geek and I approve of this video! I also want to say how much I appreciate you calling out the differences between power ground and signal ground!! I couldn't imagine trying to troubleshoot the issues that you would run into if you proceeded on the assumption that "well, ground is ground" and tied things together!! Pure nightmare! Lastly, I am not going to be surprised that from an electrical standpoint, it will work but I will be amazed! The only thing I have to say after that is good luck coding the control units to make it all work in harmony!!
Is it weird that I would actually LOVE to tackle a project like this?? Genuinely, I could just get completely lost in it for months and when it was done, I'd probably feel a little sad.
Coding the control units is going to be a whole other project, too. It won't be anything like having a tuner make a few tweaks here and there; you're probably talking at least some bare-metal coding of microcontrollers. Weeeeeeee!!! :D
lol now that he got your approval i am sure he will immediately be relieved.. it never cease to amaze me how special some people believe to be while commenting....
Now, wouldn't a signal ground be directly connected to the module though? I built a CNC table from scratch and nothing is grounded to the frame. Every sensor or trigger is a closed loop back to the breakout board. Each pin out, has its own ground next to it.
Now in the board, and software, you can wiring up all the homing switches in series to 1 pin. How the software remembers which switch is thrown I never could wrap my head around so I had enough pins so I wired each switch to its own pin. If something malfunctioned, I could isolate the problem switch immediately. Sure it meant 2 wires to each switch but 22 ga wire was cheap.
@@buttkicker8512are you one of those people that think they are super duper special?
I was going to make a similar post - a ground is NOT always just a ground. Changing the location of the fuse box could also introduce some gremlins for a variety of reasons, wire length, EMI/RFI, etc. These sorts of projects rarely go perfectly smoothly - hope it works out, but we could see some interesting troubleshooting videos in the future.
The wiring loom guy is truly a master if his craft. I fully understand what is involved, and can only take my hat off to him for embarking on this epic journey. Sectioning the loom is what McLaren should have done in the first place.
Adam is "to be accurate" a saint
I doubt he is doing this for free. Maybe at a reduced rate for a friend but the hours ... the hours. If he were charging his "regular" rate I'm sure it would not be fiscally practical to get this nightmare harness made. Better to order from factory and wait the year for it.
This whole video has me wired.
As an aerospace engineer who specializes in harness design and manufacturing, it takes a lot of time and effort to put those harnesses together. Respect for you guys especially since you have to piece it together with whatever documentation you can find. By the way, that type of connector is called BENDIX (as in BENDIX connector) and it complies with a military specification (MIL-SPEC) regularly used in the defense industry. Those connectors are a very old but reliable as hell technology.
Two things amaze me when it comes to Adam: First, he's so extremely chill about this completely insane undertaking. Like "ye this is pretty big, ye". Second, he's so structured that it blows my mind. He said 2 weeks comparing 2! harnesses?! What?! Just going through one is crazy enough
Idk what Freddy is paying Adam for making a brand new harness but he deserves every bit of it and probably more. The labor hours for this job must be insane
50000$, the title says.
What a hot mess!
Kudos to the Smartefi guy... all that talk of ECU, CCU, and TCU left me ready for the ICU...
Thank God for geeks!
ICU too, see what I did there? I’m freaking hilarious 😂
Great job!
From a guy who used to splice cables with up to 3,600 pairs of wires.
One at a time. . . . .
I also had to tone them out by the 10's of thousands so I can appreciate your awesome work. 😊👍
wow ! im a electrical engineer and you lost me, hats off to Adam , gold medal for his understanding and work on this project
I made a harness for my crashed damaged G-Wagon. Thanks for the inspiration.
I’m amazed you guys are able to tackle the wiring on this car! I’m a little bit of a wiring geek, with regards to electric guitar and a little bit of car audio, and I can’t begin to comprehend how overwhelming what you’re doing with the wiring would be!
Congratulations Tavarish, for your own knowledge and wisdom in assembling a worthy team of knowledgeable people to accomplish such a great feat. You are indeed the consummate General!!!
I am glad that you dedicated a solo episode to the wiring harness.
Lets go Tavarish! By far the greatest automotive youtube builds by one of most genuine guys to do it! Cant wait to see the P1 come back from the Gulf! 🔥🔥🔥
I once made and rewired a vintage lorry and it worked it was a nightmare as the drawings I worked with were incomplete also I had to update it to 12v and that was child's play compared to this. Adam hats off to you.
If this mans business is not popping off after this MOUNTAIN of a project i dont know man. It is insane and pure dedication. I love it
Normal people have no idea what a project entails.
Bravo loom guy!
A Sunday upload - what a treat!
I thought I was cool for custom making a wire harness for my car radio when everyone includeding pro shops and UA-camrs I reached out to told me it wouldn't work. I had to build it better! This is insane and congrats to you and your tribe for finding a way to make it work.
I’m gonna enjoy this, I used to build the weapons system wiring harnesses for the F-35, did work on the A-10 and KC-135. Good luck! Remember to put the heat-shrink tubes on the wires before you pin out the back.👍🏼
say “Amphenol” three times really fast 😂
@@mauraece lol, yea a lot of Amphenol, they’d be lucky to have Amphenol built electrical harness.
I would have started this project by creating a bed of nails board to fit to the original wiring harness, then modify it to the new connector placement requirements, then build the new harness on that bed of nails board. All in the electronics industry, complex wiring harnesses are built on bed of nails fixtures, for every kind of device up to large aircraft harnesses.
the drawing on the table is essentially the same thing. Just quick and dirty but easily as effective for a one off project.
I thought those were for laying on….
Oh god, mouser bags full of molex pins are the stuff nightmares are made of! No wonder matey started screaming when he saw the table lol....
This is a very brave man indeed
God bless you and the sphegetti god thats helping you. I cant wait to see the end result.
Truly, this is the work of His Noodly Appendage. Ramen!
(1) spaghetti, not “sphegetti” 😂. (2) there is no “guy in the sky” nor a god for spaghetti.
I cannot fathom just how daunting of a task that wiring must have been and how stressful it must have been at the beginning and the planning stage. Also, twisting every wire by hand...the real MVP of this project, this is nuts and I wish I had this mans work ethic
Is that matt Armstrong's Audi under the ramp in the background?
Yes it is.
The complexity of this project is crazy and this really demonstrates just how much is involved but this is going to be the best P1 on the planet! I think it should be the P1-F for Freddy! 😂 ❤
I have to admit I had contact anxiety just trying to imagine making sense of this wiring challenge. I have faith in you guys to work it out... you got this. 😮
24:18 "you're on your own" in back got me Its a road side assistance T-shirt man
Dude is a wizard of his trade very impressive... the quality of the work and the knowledge is just insane. glad that you found some good dedicated people to get onboard and help with this big project.
Adam is a genius, without him this build would be a combination of non compatible parts
Not a genius. He’s a professional. We need to celebrate hardworking technicians.
I'd say both.
This is why I like to watch content on UA-cam
Once upon a time, years ago I was tasked with building a tamperproof wiring harness for a Bahamian rental car business, That was Nothing like the complexity of what Adam is doing, but it was significant given the technology of the day and components available in the Bahamas. Kudos to you both!
to summarize a 37 minute video. IT'S WICKED HARD 😁
Wiring and electronics: the worst thing about modern cars.
Which car doesn't have them?
This is the best thing when everything is disassembled in the car 😄
@@someguyshittalkingCybertruck ethernet
For sure
the P1 is 11 years old.
Savant level mentality needed here, not a bad thing. Huge props to Adam!
It’s so awesome to watch this project inch towards completion. I also love that the shop is so organized! Thanks for the Sunday upload fellas.
Bless you Adam. You must have the patience of a saint. Where do you find someone to do this???
Its gonna feel so good when it all plugs in and works its like frankensteins monster
I pondered just how much work the harness had really been when I watched your main channel. Quite pleased that you expanded the views of what that job really entailed. The fellow doing the job is earning a big big bucket of respect.
Excellent. The right approach to creating a logical loom. Love it
You keep posting part 1 videos, but we never see p2?
Thanks for the tutorial, this will come in handy for my flooded P1!
I love wiring and circuitry. That looks like fun to me.
Wow what a patient guy Adam is! He has put so many hours into this and I can’t wait for him to see the fruits of his labour. He deserves a medal
I really enjoyed this episode- I watch ALL your videos. As a Master Electrician, Electronic Engineer, Marine Electrician and now Electrical Contractor in Hawaii I have worked on everything under the sun Electrical. The patience it takes do what you are doing is incomprehensible- Can't wait till your masterpiece in finished! Hurry up!! But don't leave us out! We want to see everything! Aloha from Hawaii Team Tavarish! Flash the Electrician
Give that guy a raise or something, bro looks absolutely defeated, probably has nightmares about wires 🤣
Thanks for the heads up about the next series of Wheeler Dealers!
Adam, you are an absolute trooper and have a tenacious attitude! I feel if it can be done he will do it.
this wiring harness is an awesome undertaking.
this is excellent content.
I thought this was a second upload this week until i saw 2varish mashallah!
Adam is very meticulous at his work. Dude rocks. Tavarish is so lucky to have good people working for and with him.
the wiring harness 100% easily the most complicated stuff to fix for the car. Mclaren got entire division of experts to design the harness and assemble them. Adam is truely the MVP of this project and the one who will be responsible to bring back the P1 back to life, and he is doing it single handedly. if this idea of bringing 2 harness into 1 and build it from scratch every single wire and connector eventually pays off. hands down Adam is the hero. Respect to you Adam to take on this project, hopefully all goes well and the P1 will be born to life again.
Man McLaren missed out on this project big time this will be the most famous P1 on existence when it's done
The attention to detail that's going into this car is next level. Maybe even a level above next level, next, next level!
My family knows i’m down bad in fixing cars and that, HOWEVER they don’t even imagine i’m watching 36min of 2 guys talking about car wiring and harness down bad 😂😂
BTW awesome job, awesome people, and hopefully soon… awesome McLaren keep it up guys you are living the dream, or kinda?
Thank you for this video - it answers some of the questions I had on the previous video. The continuity testing day sounds like good fun!
The splitting of the cable into sections with those fancy connectors seems like a very smart move.
Wow!! This is what i call the right nerd, for the right job!! Amazing- I’m certain Adam & your team has got this!
Amazing work! What a massive project! So many fine details involved...
This just seems like a monumental undertaking. Saw the other vid when you had the dash waking up. Zero doubt you will have this thing squared away. Looking forward to watching you guys bring it all together!
wiring really is the hardest part. This is just madness and it is impressive.
I think this p1 project is epic and history on YT everyone wants to see how Freddie innovation will work out in the end. Every upload has something interesting and suspense. Keep them coming Freddie ❤❤❤❤❤
And now I have a headache. Adam is the real expert on this project and he has great perseverance!
Got to keep all the information from your findings.
No one else could ever go to these lengths without a helping hand from your experience on a P1. Fu k knows how you manage it 😂
Some people enjoy this kinda thing, but Adam is a beast for this… 50k is cheap
This
Is
Nuts
You've got the right man for the Job on this!
Love seeing the complexity and yet how much is similar and different at the same time!
This is a major project and I can't wait to see everything working properly and this P1 come to life!
Insane Amount of work
💯 Respect
It's like a complex nervous system... fascinating.
Simply nightmare fuel! Hats off to anyone willing to do this ! 👏👏👏
Hi couple of things to mention about wire. I work in a very specialized wiring company. Firstly you can't just twist wire together by hand never with a drill, you have twist lengths, and twist tensions, as not to damage the outer layers. The type of wire you use, not only doe's our company put wire into space and at some of the deepest oceans, we do some of the very top sports cars. Fire and melt properties and mostly weight. Heat and fire resistant for F1 cars and fifth gen / sixth gen fighter aircraft. Most failures for wiring is environments, movement, and other points what each wire signals pass with the correct noise protection given to each component. For Very special advanced moving vehicles needs the most advanced wire. Very good luck love your channel.
say “Amphenol” three times really fast 😂
If not by hand and never by drill, then what is the correct method ?
@@mauraece Good luck then why not just use house wire 🤣🤣
@@OneOut1 A Quad machine, the unit SPINS the wire together at correct twist lock and tensions as to not damage the components if you put more then 3 wires together they have to fit with each other. when you build large cables of all deferent gauge size all has to be built in the correct order. (you cant just grab a bunch of wire and put tape around it) that's why it cost 20,000$ a loom.
Oh Look a repeat from his first channel..
continuity is a good check but always remember that continuity will not let you know that it will carry a load .on some of the important power items and wires i would load test to 100% verify
I breathed a sigh of relief when you acknowledged your understanding of the grounds and their need to be separate. Typically, when you see twisted pair, it's communicating via a databus esc protocol. Unless you've worked on, or spent countless hours troubleshooting anomalies, you may not understand the frustration grounds can cause. There are circumstances where only one end of the wire is grounded while the other is simply terminated & if your night shift counterpart mistakenly grounds it w/out you knowing, an entire system will stop transmitting/receiving. Look for those mil-spec connectors on surplus sites, likely save you a fortune. I can't wait to see this thing finished.
Oh My God! This episode is going to rock. Wiring harnesses are my favorite. 😂
That's nuts. How could you impose that massive task to you friend, Tavarish? You're a monster.
Adam is a genius. Very interesting video. Great to see what goes into all this and to have explained so well.
Adam!!! My God your talent is amazing.
There are very few people on this earth that can do what Adam can. What a talent.
Good luck on the wiring always look forward to your videos can’t wait to hear the p1 start
Dude is a wizard with wiring!! He's the real mvp if you ask me.
Sounds like you have the best man for the job! There cant be many people around as knowledgeable and patient as Adam. Those wires have headache written all over them to me :)
Visiting from Michigan and happened to drive by your shop and SO wanted to drop by and possibly see you and your famous P1, but thought it would be invasive. Good luck with this project.
