How to Splice a Factory Wiring Loom [THE SKID FACTORY] 

Turbo yoda is actually brilliant. I feel like i owe him money for watching this video

54 minutes of listening to Al. Today, is a good day.

This video is a gold mine of information. I've been doing a lot of work on my Integra, and have been tossing around the idea of slimming down the harness and tucking it, this just put me over the edge, thanks a bunch! Thanks for sharing all your car knowledge with us over the years.

it may be easy if you did it 500 times, but also being able to teach on camera and do that at the same time, really shows you are an expert

Loom work is an art, and i could watch any savvy person work a loom for hours. Alan is amazing in this. Much respect to the people who have the patience to do these the right way and not make a rat's nest of their looms.

An hour, holy crap..... This is gonna be maaddd.

I spent over 2 years building electrical harnesses in the aerospace/defense industry, and seeing this harness get worked on is giving me horrible flashbacks. Still watched it all though, Mr. Yoda is totally worth it lol

Anyone who has a chance to spend time around you and learn and be educated is a very lucky person, thank you for your knowledge!

I'd pay money just to sit and watch him work ..this man is a simple of a genius as they come

I am glad it was explained why just using an aftermarket ECU was not done. Makes a ton of sense, seeing how so many laws for that stuff is so different across the globe.

Holy shit. This is the wiring holy bible. More amazing comprehensive videos like this please! Seriously, this is awesome!

Once again Al provide actual tested knowledge, instead of the more common occuring ”I think’s” on youtube. Absolutely brilliant ! Thank you and keep it up 👍🏻

Al did my harness splice a few years ago absolutely flawless... thnx al👍

Being able to do this type of wiring/troubleshooting is the car worlds equivalent of a brain surgeon. The technical details are often too tedious for most people to have patience for. I have to say *Thank You* to Al for putting this information out to us and taking the time to explain what he is doing along the way. This is the type of skill you cannot learn from a book. All the little details along the way about spacing/length certain connections, tagging and not keeping the looms separate are things you can only learn through experience. This video and all the information Al has given is priceless. Thank you for sharing with us!!

now.. this is the kind of video i can put to use for my own projects.. and an hour long, time to get the popcorn :')

So glad you made this . It will show people just how much work is involved with just the wiring .

This takes a special form of patience and i'm grateful for those that have it.

i have been studying wiring fuse boxes and relays boxes, because i have really been wanting to go thru the inside harness, its been 5 years since i swapped a ls1 and now after watching this, there will be no way i can stop myself from de-pinning the fuse and looming the whole thing. you really are giving us great tips.

I just binge watched every video on the channel and wow is it good. I have so much confidence working on my old JDM car now I can fix it.

Having done this before for different cars, I thought I was good at it. I now realize how easy I had it. I could put the wires on the connectors of the car to route everything and get locations... SOOO much easier than measuring all of this.

The skid factory is the best car channel on the web. Love it

This is why I am glad my 928s have multiple electrical harnesses and subharnesses that connect to them. Best part is the fuel injection harness is completely independent of any other wiring. I could never go through the trouble to do harnesses like the ones shown here. Great video BTW.

What a guru! Absolutely priceless learning from someone who has learnt the best way to do something over years of experience.

Thanks Al and Woody for the excellent tutorial. This is what youtube is all about. Al, as ever concise and engaging. As a mechanic (same vintage), I could watch, listen and learn from you fellas all day every day. Thanks again.

It's so awesome that Al gets to show off and teach from his years of experience. I'm keen to see more videos like this!

This vid is brilliant. Thanks for sharing the depth in this video. My favorite part is when Al is wrapping things up and says that it took him 10 hrs, but based on his beard and hair growth, it looks more like a few weeks. Thumbs up for wire and video splicing!!

when I first saw it, it had been up for 8 minutes and had 127 views, now that I finished watching and refreshed my browser it has 2500 views. Thanks so much Al for sharing your knowledge and skill with us, it is an honor. Thanks Woodie for taking the time to film this and all the other things you do (and you bloody well BETTER sweep when the master tells you to!) to make this video happen! Cheers from Canada!

We use millimeters as a measurement often in America and learn both systems of measurement but rarely use the metric. I could ride in a car and tell you when we reach a mile but would count 3 miles if you quizzed me on a kilometer and how I came up with three miles I haven't a clue. 😅Aussie lingo, when describing a activity or process... I noticed aussie's will just say the action to describe a entire process rather then a entire sentence. I love it, clear and to the point.

Thank you Skid Factory crew, Turbo Yoda, and all the rest of you! I needed this video, thank you so damn much!

Skid Factory thanks for the inspiration! This is the one aspect of Subaru legos I haven't personally done, after decades of multi Impreza ownership. You've unwrapped the mystery with straight forward instruction, and pro tips that can only be learned by doing this 100's of times. I'm going to try it now. OBS Bugeye is getting boosted. Thanks again guys!

This is a great video to convey the amount of work that goes into any wiring job. Thanks for sharing the projects that many people find "boring". I wish I had seen this before I rewired my 1975 Mazda from scratch.

I’m pretty good with mechanic type stuff, I’ve torn transmissions apart and put them back together, engines, etc. but this type of stuff wiring harnesses, and connecting two different ones together, that’s just something totally foreign to me, I’m trying to get there one day but this is just so beyond me right now lol thanks for the vid, you are a true expert on this craft sir

Hi guys, I mentioned previously that I really like what you guys are producing and hope it is economical for you to keep it coming. I'm sure you won't mind reading it again. In my old age I'm critical as to what I watch but go chasing latest report every week. Cheers.

I enjoy watching videos of Alan work and talk. Methodical and logical. Its great. He reminds me of my old man

If that doesn’t deserve a beer I don’t know what else does, thanks to all involved in the making of this video true in-depth detail both in front and from behind the camera. Keep up the great work

On behalf of all of us, thanks for taking the time to make this video. As a fellow electrician and a subaru nut I understand the the love or hate relationship haha.

This is just an amazing video. I have done some wiring for engine swaps, but we never had to go through the loom like you have demonstrated here. I am building a custom wiring harness for my 65 MGB, and I know I will be watching this video again, just to go over the tips you have presented here. Thanks so much for showing us how to do this correctly, and safely.

Not as exciting as an engine swap but I enjoyed it and appreciate the effort you put into making this video. Thank you!!

mcmtv2 is Al's channel now... Keep up the awesome vids guys

Really grateful you decided to make this video, all the knowledge in the world doesn't hold a candle to years of actual experience.. Thanks for sharing valuable experience with everyone. I've done this done this a few times and still learned heaps of great tips from this video.

Amazing. The best in-depth automotive technical video to date. MCM needs to step into this realm. Better than Motortrends current programs by a long shot. THANK YOU!! Keep this exact formula and expand to other swap/automotive project areas.

I'm in the middle of putting a toyota 5mge into a 93 toyota pickup and I would have to agree on everything he said. Don't think of starting unless you have ALL the wiring schematics and go one wire at a time. It can be done but it takes a lot of time.

Alan doesn't specifically say this, but the reason why you should never, ever let the loom run loose (or worse, take it apart completely) is because the loom is made on a jig, with tolerances, and if you start messing with order, length, position, tie points etc, you risk changing its architecture and the way it behaves and that's when wires snap, twist and break in the sheath etc.

If I did that to a car it would never run again! This is a very rare skill nowadays, and you are lucky to be able to find someone with this kind of experience.

High quality video guys! Very indepth and informative, which in my opinion is what a lot of channels miss out on to save on time & editing.

Absolute genius what a guy. Turbo today for the win 🔧

Yessssssssss. Video we've been waiting for!! Watching Al building a wire harness is watching a master craftsman at work.

how to sploice

great job, Al. Very complicated and responsible.

This video is about to hit 1 million views by tomorrow !

having done this for the first time recently i can say with confidence that A. i wish this came out earlier because it would have made things much easier lol and B. alan is an absolute wizard. this kind of job is probably one of the most difficult things you can do in the car world (definitely easier to just make a standalone harness from scratch which i have done more often)

I have done alot of motorcycle race looms and I'm glad we follow very similar ideas. Glad I've found the channel 😅👌

"Does that make your blood boil"..."nah, just makes me weep for humanity"....yeah I think that's worse hey...lol This vid will help me rewire the 180...exactly what I wanted from this channel, thanks guys ;)

such a good idea for a video. nobody has tackled this properly on youtube yet! sooo good

I've been on both sides of the student / master relationship over years and it can be very rewarding to have either. When both people have respect for each other it can be a bit magical. The student can pull an insane amount of knowledge and experience out of the master by asking gentle questions, and the master is there to make sure the student does things "right". Usually, they will have a great deal of pride in a good student. When the relationship is right, it's not a school, it's a friendship that sticks around through the years. It's great to see that sort of thing alive and well today. Turbo Yodo makes boring shit .. well .. pretty interesting. This channel is a fountain of practical knowledge and this channel has grown to be one of my click-immediately channels. I hope this comment hits home a bit more than the usual disparaging 'tube trolling.

Thank you guys. This is exactly what I was looking for in terms of wiring. I had an idea but this was a great help and video. You're the best Al.

Use a seam ripper (from any sewing equipment store) for stripping the wiring harness. Much easier and faster than using a razor blade.

I love these videos. Don't get me wrong, the usual MCM videos are wonderful, but this is the type of stuff that we really don't get to see because it is usually condensed because of time constraints. Turbo Yoda, thank you, for taking the time to do do this. It is truly appreciated.

Right up my ally AL!!! The part some people don't like. Gotta love wiring! :)

This is a awesome video to learn wiring. Very in depth. I like. Turbo Yoda is a smart man!!

thankyou for calling out the issue with aftermarket ECUs, the frustrating thing is that some older ECU's are now failing - just spent 600 dollars getting a 1UZ ecu repaired, a Modern ecu would sure be more reliable but as you say, the testing to make it legal is difficult and very expensive.

"Don't chuck it in the bin, you don't need any more waste in the world." Wise words!

I work in aircraft electrical which is very standardized. Auto electrical drives me crazy! It's all over the place! The way they control circuits with grounds or power. And Jesus automotive plugs mostly suck! There are a million flavors. Great video guys this needed to be done.Turbo Yoda is a bad ass!

So what I got from this video is... When you pay someone to do this, it's money well spent. :p

i did this once to my R31. spliced the front half body loom into the rear half and added power windows and cruise etc the whole box and dice. Thank fuck i had the factory workshop book. It kind of gets fun after a while hahah

I appreciate the video and info; I've done two merges on my Subarus so far and definitely learned along the way. Using reference points for length is a great tip. Thanks!

Awesome episode. Thanks for the tech Al. Took me 3 months off and on to do the harness for my Jeep LS swap.

Good information, very much appreciated. Greetings from Romania.

Wish i had your knowledge after 501 times bet you could duit with your eyes shut or while sleeping :) keep up the great work guys.

Very nice video !!!! I enjoy these Harness conversions No matter that Make or Model .. continue making Great videos

very informative... loads of knowledge shared. thanks... only disagree with your use of crimp connectors because of oxidization will create resistance at the joint over time. where as solder will prevent this happening

Awesome video. I did my first efi swap after watching this and I used a lot of the advice. 👌

This video is timeless

Dude, that's a simply awesome tutorial! Great information and very useful tips! I've been doing wiring in cars for quite a while now, but I haven't got nearly as much experience as you. It was really useful watching this. Keep up the great work! Greetings from Bulgaria!

Yep, that's a pro at work right there! Just goes to show a) how much work and knowledge is required, and b) why you pay a specialist - and it took him 10 hours!!

Looks like Yodas hair grew by the time that loom got finished geez. Awesome vid none-the-less. keep it up guys

Really like this one! I have wired a few cars and its nice to see a different perspective on it!

I love it when turbo yoda likes to reuse stuff such a good guy

Ahh, I'll be rewatching this countless times I'm sure. (I'm doing a 2005 jdm Spec C motor swap into my usdm 1998 L coupe)

Alan: Just keep it all together and tape as you go or else its never going to work again Also Alan: Im just going to untape everything because I know what Im doing and have haeps of experience Haha - just teasing. Love the video and all of the excellent information you shared!

The knowledge of Turbo Yoda is impressive. This guy can do anything.

Instructions unclear, accelerator now controls windscreen wiper speed.

I lease a bog standard white 5 door Golf with all servicing, insurance, breakdown cover included, own no other cars and love watching this show! but I like my life simple.

Alan comes off as very Dry, which i think is the getting taped aspect, but incredible wealth of knowledge for sure. Also the amount of innuendo, with no giggle or "phrasing" or thats what she said.. I know, cliche, but im siting here saying phrasing each time. lol. Will be buying merch to support the channel for sure! Also im doing a JDM non avcs ej20 into a USDM NA Baja right now, so this helps with the.. I hope i didnt cut off to many of the wires. For those trying t find another resource, rs25 Forum - Brydon teaches to wire.

Kudos on a great video, furthermore, I applaud you for saving the tubing instead of just throwing it away.

I dont even own a car yet I still found this helpful

Your hair grew heaps in 10 hours!!! LEGEND!!

Is there anything Al doesn't know? Guys a legend

Turbo Yoda, all respect and gratitude is given to you because for so long I have wished to garner the knowledge you have and now you give us this. I thank you because my love for knowledge knows no bounds when it comes to cars. To see you work and do something I render as impossible, become possible with your skills was nothing short of amazing. I wish to see that you grace my comment with some advice for an aspiring master technician of knowledge. How did you get so good and what do you do to further not only your skills, but your knowledge as well?

Hey Al, even if you charge me a $1,000,000 I’m still gonna get you to do all my wiring, you are amazing!

Hey guys love the video and great information. Time-lapses are awesome for this sort of work and lets people watching see more of the process.

Full hours worth of custom wiring how to's and tips?.....

This is full on nerd stuff and I love it! I'm currently trying to figure out the wires on a Bose Amp from a 2003 Altima and this video was incredibly useful. I was trying to match the wires based on a couple of internet sources with the corresponding colours. I now realize that they might be different. This changes everything. The only thing I would do differently based on my complete lack of experience is, I would use a different colour electrical tape for the other loom so when they are placed on top of each other I wouldn't get confused.

The soothing voice of Yoda makes all problems go away.

WOW, An hour long episode!!!!

That’s why I like the BMW swaps I do. The engine harness is almost completely separate from the chassis.

Love where the industry has gone over the years. Remember guys cursing manufactures for bringing computers into veichles. Today we can take just about any factory computer, flash it (within reason) to our liking while gaining a performance goal, and still street legal.

A wealth of knowledge there folks...

Damnnnn, al hair grows fast 😂. I’m not gonna lie, this is wayyyy above my knowledge but thnx to al, I’m not completely lost. Hopefully with practice I’ll get better.

Great informative video. Also great to see how comfortable Al is in front of the camera these days. Still need some different mics as he speaks so quiet!
