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.

Adam is the MVP of this project. This is crazy

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.

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.

Respect to the loom guy that’s a massive undertaking

As an avionics technician, I used to wire military helicopters. Kudos to you guys taking this on.

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!

Whatever Adam is being paid for this work isn't enough. He's definitely earning every pretty.

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! 😮

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

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!

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!!

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!

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!!!!

Adam is "to be accurate" a saint

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.

This whole video has me wired.

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

wow ! im a electrical engineer and you lost me, hats off to Adam , gold medal for his understanding and work on this project

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!!!

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! 🔥🔥🔥

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.

I made a harness for my crashed damaged G-Wagon. Thanks for the inspiration.

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

A Sunday upload - what a treat!

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

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. 😊👍

Wiring and electronics: the worst thing about modern cars.

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!

I am glad that you dedicated a solo episode to the wiring harness.

Normal people have no idea what a project entails. Bravo loom guy!

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!

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.👍🏼

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.

Excellent. The right approach to creating a logical loom. Love it

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.

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.

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.

Thanks for the tutorial, this will come in handy for my flooded P1!

I thought I was cool for custom making a wire harness for my car radio when everyone includeding pro shops and KZfaqrs 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.

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! 😂 ❤

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....

Adam is a genius, without him this build would be a combination of non compatible parts

to summarize a 37 minute video. IT'S WICKED HARD 😁

This is why I like to watch content on KZfaq

Thanks for the heads up about the next series of Wheeler Dealers!

this wiring harness is an awesome undertaking. this is excellent content.

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.

Amazing work! What a massive project! So many fine details involved...

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!

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

You keep posting part 1 videos, but we never see p2?

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. 😮

Love seeing the complexity and yet how much is similar and different at the same time!

Its gonna feel so good when it all plugs in and works its like frankensteins monster

Bless you Adam. You must have the patience of a saint. Where do you find someone to do this???

I love wiring and circuitry. That looks like fun to me.

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?

Some people enjoy this kinda thing, but Adam is a beast for this… 50k is cheap

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

Savant level mentality needed here, not a bad thing. Huge props to Adam!

Wow!! This is what i call the right nerd, for the right job!! Amazing- I’m certain Adam & your team has got this!

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 ❤❤❤❤❤

This is a major project and I can't wait to see everything working properly and this P1 come to life!

It's brilliant to make the harness in sections. It allows for better diagnosing and much more manageable to work with, especially with installation

I thought this was a second upload this week until i saw 2varish mashallah!

Give that guy a raise or something, bro looks absolutely defeated, probably has nightmares about wires 🤣

It never crossed my mind that ‘loom repair man’ was a job, let alone that to do it, you needed to be an artisan craftsman. This guy’s an artist

The attention to detail that's going into this car is next level. Maybe even a level above next level, next, next level!

Insane Amount of work 💯 Respect

Absolutely one of the best videos ever

Adam is a genius. Very interesting video. Great to see what goes into all this and to have explained so well.

This Is Nuts You've got the right man for the Job on this!

Man McLaren missed out on this project big time this will be the most famous P1 on existence when it's done

Adam!!! My God your talent is amazing.

Well done! Amazing work

wiring really is the hardest part. This is just madness and it is impressive.

The splitting of the cable into sections with those fancy connectors seems like a very smart move.

Simply nightmare fuel! Hats off to anyone willing to do this ! 👏👏👏

I have a huge love for cars....in all honesty I'll probably never own a super car in my life.....The insight and education people like freedy give us all into these Unreal projects is amazing the fact he has the sheer bollocks to put his ass on the line and create this content.....blows my mind. Thanks Fred love ua bro.

It's like a complex nervous system... fascinating.

Oh Look a repeat from his first channel..

Wow just wow this is amazing. Great work 💪

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.

Dude is a wizard with wiring!! He's the real mvp if you ask me.

Adam is very meticulous at his work. Dude rocks. Tavarish is so lucky to have good people working for and with him.

Oh My God! This episode is going to rock. Wiring harnesses are my favorite. 😂

Adam, you are an absolute trooper and have a tenacious attitude! I feel if it can be done he will do it.

Hats off to you guys, you're doing an awesome job. Listening to talk about the various systems, it's very impressive what you have learned through this process. I enjoy learning some electronics with Ardunio, seeing all this makes me smile (yep I'm a geek) but what a massive job. Would love to know how you go about learning to re-program ECU's etc and how on the main channel the BMW dash cluster displayed the McLaren. I'm guessing some CU is actually outputting what needs to be displayed on the cluster. All very interesting stuff 🤓 Keep up the amazing job Freddy.

This guys is amazing. Total stud.

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!

Always loved wiring and the trouble shooting that comes with it!

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!

Love love love your project and grateful grateful grateful that I'm not the one doing it

A very patient intelligent guy 👊🏼I give you a lot of respect for the hard work and dedication 💎

Just INCREDIBLE!!!

Good luck on the wiring always look forward to your videos can’t wait to hear the p1 start
