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!

[@KG-yn9qi]

@Lassi Kinnunen same color?

[@Mrcaffinebean]

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.

[@SchielMusic]

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.

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.

[@Jafromobile]

Money! I feel like that's the most appropriate answer... 'cause once it's got all that, it's time to put 'er to work!

[@WelcomeToTheMadness]

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!

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!

[@another1commenter770]

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.

[@nismofreak33]

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.

[@Jeffball610]

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 :-)

[@timramich]

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.

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 KZbinr'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!!!

[@Jafromobile]

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 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!

"It's like a fart in a spacesuit" I've gotta find a way to work that into one of my zoom calls...

[@burkestrand5070]

loved that analogy

[@peterk2455]

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.

aww dude a squeaky shoe is the worst. you sound like a cartoon character everywhere you go

Clown shoes IRL.

[@crazyasspotter]

Might be time for some new gasket material?

[@DavidKing-gl9tz]

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

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!

[@Jafromobile]

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.

[@muttenmagroo]

I did this job on my Celica Alltrac st185 about a year and a half ago. I did use a donor harness from an NA automatic but I still had to redo all the injectors,coils, and cam/crank sensors. I think studied the factory service manual for about a month before I dove in and it still took me almost 2 weeks to get it all proper.

[@Jafromobile]

Mine took close to 3 months once I started because day job and life and screw ups and editing. It took me years of fixing and poring over the service manual, and battling never ending problems to motivate me to do this. I confess that vendors still having the parts to do it was a huge motivator, but if that's all it took, you make Thomas Edison look like Slowpoke Rodriguez.

[@muttenmagroo]

@@Jafromobile well I did use a shortcut with another harness, mainly because of cost. Sourcing all of the wires and connectors added up real quick. Main reason I did it was for the body harness thats tied in to the engine loom. There was very little info on it other than what I could find in the factory service manuals.

[@Jafromobile]

@@muttenmagroo Maybe it was the same guy that wrote both service manuals? Yeah it does add up quick. I spent over $1,600 making this video. Definitely a big ol' loss, but this needed to be done and put here. It was the body connector for me that made me re-use any of it. If I found a brand new 21 pin connector in any of my searches, I'd have tried a little harder to find brand new RF shielded single-filament 14-gauge wire. Probably only available in a 500 foot spool, and would have spent close to $1,800 instead. Forums are full of "where can I find shielded o2 sensor wire?" and with no good answers. For each of us struggling with this, there's someone out there who knows exactly where to find it.

[@tonkatoytruck]

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.

[@m.a538]

Thanks for posting this. Super interesting

[@kellyappel3015]

Your wire striping tool is awesome. Nothing better than simple, cheap, and functional.

[@Chippy569]

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.

[@falconklaws53]

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

[@scottkennedy7834]

Over an hour of Jafro. Best day on youtube since BOM had a new episode

[@Jafromobile]

I love those guys! They're the best thing that ever happened to the Austin Mini and KZbin. I'm enjoying the Escargot as much as Binky, really.

[@scottkennedy7834]

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

[@Syncopia]

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.

[@Jafromobile]

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!

[@HUBBABUBBADOOPYDOOP]

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.

[@Jafromobile]

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!

[@waynejamel]

From Henrico va., you are a genius , I have always wanted to make my own harness for my 90 tsi. Well done sir

[@nezerac]

@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.

[@curtisroberts9137]

Never had to make a full harness before. I've had to replace a complete harness on a 2018 chevy pickup. That was enough work! Building the harness from scratch... NO WAY. Beautiful work, professional, and a great looking product. I'm guessing you could make some money selling harnesses now.

[@kip_knomore]

Seriously impressive....all of it....i ran across your video when researching how to fix the wiring harness on my car and found myself feeling shamelessly satisfied watching the precision of your work....lol 🥰 Thanks for sharing!

[@kevin55950]

Men, I call this education! Thank you for this video. That will be so helpful for people getting in this passion to see what it takes to complete a job or even, just to see how it's made. As always, thank you for taking the time to film these amazingly long jobs just so we can learn something from it. You have a new Patreon. Keep up the good work!

[@DigiTuben]

Love your videos and have been following them/you for YEARS (an understatement considering it's been over a decade), just became a Patreon. Your contribution to the DSM community is un-repayable/priceless! Love your work, time, dedication, drive, motivation, and attention to detail. Keep that brother, you are a true hero to this community and many more people/communities to come in the future!

[@89Mirageman]

Long time Jafro fan here. I've been referencing your videos for years and every time I've had the chance I've linked others to your videos. But there's just something special about this one and it's my favorite. I can relate to the amount of work that went into it, not even counting documenting it. You sir are a boss. I watched every second and I'm sure I'll reference it many more times in the future. Sincerely man, thanks for taking the time to make these videos. They really do mean a lot to us!

[@Phenixzero]

This is awesome work! I believe EVERY car owner, specially those who ever owned a nice beloved 90’s ride would love to have such a great work on their car!

[@nameboy3486]

I watched the whole thing it was great. my fiance comment how you show every step and i told her i learned how to properly assemble an engine from your videos.... keep it up, thank you, and be safe

[@latestplague3762]

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.

[@Jafromobile]

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?!

[@latestplague3762]

@@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.
