Great video. I’ve got to upload a video one day on making a harness from scratch. I like rebuilding my engines in-house for my company, and when I do they got back “deleted” (diesels). What I do is buy all new plugs for what sensors are left on the engine, put them all in place, and run wiring from each sensor back to the ECM. I use fibreglass braided sheathing thats dipped in acrylic, I then place a 1 inch piece of shrinkable tubing half over the sheath and half over the wiring going into the plug. I use varying sizes of sheath as the harness grows in size. The great thing about the fibreglass braiding is it’ll take up to 500 degrees without melting (way higher than the wire will take). The result is a million mile harness, thats neat and free of extra plugs from sensors that are no longer in use.
Another way in wrapping the harness with electrical tape is to wrap the tape sticky side out and then go back over it sticky side down. It adheres well to it self and it doesn't make the wires sticky.
I own a D350, glad I saw your video, started fixing relay today and decided to pull all the wiring harness and make it look good. Thanks
I've done my fair share of wiring harnesses and I can tell you that adding vinyl non-stick tape to the harness, before you add the Tesa tape, does wonders for making sure the harness doesn't turn into a sticky mess after some heat cycles. I go Vinyl Tape > Kapton Tape > Tesa Tape. I use the Kapton Tape on areas that will see higher heat ranges as it's supposed to keep heat at bay. I wrap the harness in TechFlex sleeving and use marine grade heat shrink to keep it tight. Hmmm, I may do a video on this 🤔
Please do!
Links to the tape you use please!
@@Chache1527 For some reason I can't post a link in a reply, odd. But if you search for Dry Vinyl Tape or Non-Stick Vinyl Tape you'll get some hits! The Kapton Tape is pretty straight forward, search for that and you'll have a ton of options!
@@VegasBoost awesome thank you!
@@Chache1527 Anytime! I'll be making a video on these wiring issues soon and this gives me the idea to include the parts in the description!
You don't know how happy it makes me to see the tesa tape instead of cheap .99 electrical tape
it was not too bad for restore it completely...
i hate those crimping connections.. i prefer to attach them by hand, solder them, and use heat shrink
actually, crimping connections are way better and stronger than soldering connections if they are done properly, crimping connection is not based on the friction between the cable and the cable lug as most peoples believe, crimping connection is based οn the exchange of atoms between the copper cable and the cable lug and the end result looks like this

This was incredibly satisfying to watch. Sorry about all the hate. I, too, prefer soldered connections, but I think you did a fine job here and the crimp connectors will work fine especially protected in a wrapped harness.
Great work on the very harness and on this video. In 40 odd years I’ve seen way to many dodgey jobs when it comes to wiring. Thanks for sharing 👍🏻👍🏻👍🏻
Excellent video. A useful tip somebody posted on CZcams which I have since tried out for myself is to use a sewing stitch un-picker to remove the outer protective tape from the wiring loom. This cheap little tool is surprisingly effective.
Crimp away! Used crimp for my stereo it's golden!
Can't wait to get my MR2 out of storage and do this to the wiring harness. Please keep making videos you are the best!
thanks a lot for the positive feedback! Don't worry I'm just getting started :)
thank you man honestly i couldn’t find any videos like this
good video m8.Some good comments to.I feel much more prepared than I did before.What looked like a nightmare job you made look fun.Looking forward to the renovation.1984 BMW K100 motorcycle cafe racer build.
It is important to start taping from branches into the trunk (with some overlap into the trunk as well) and then one continuous taping segment starting from a far branch through the trunk ending at another far branch and then caping that end with heat shrink. This way there won't be any chance of tape unraveling at the branches.
Soldering is so much fun, and just as quick...
In kenya we need people like you
that's a good job, man .
Perfect video my friend. i learned like 4 valuable things i didnt know.
+Luis Rodriguez thank you! Glad you found it useful.
One being on how to not repair a harness
Thanks alot this video is so nice👌helps in understanding small concepts related to wire harness
Bhai Man gaye wah ! Well Done bro !
great work man
Awesome video, would suggest getting a universal extraction tool to remove plugs and also, before removing the plug, I take a photo or my n note on a pad or something, just for the fact that if you get distracted for a brief second, you are covered
This is my job since 2000 until now 2020.. make from cutting until finish good
i just twist wires together real good with heat shrink tube. never had a problem
Thank you 😄.. this is so fun
No, thank you :)
Looks Great!
I like your videos! Keep up the good work!
James panda Thank you. Will do :)
I really like the heat shrink Connectors with solder in them. You get a crimp and when you heat the tube to close any openings it solders your connection

I have a project car I bought and after watching this video I am not scared anymore to pull out the harness and repair lol. Or should I be. Thanks Bud.
Here's a new video with the wiring harness where I went a step further. czcams.com/video/f40J85HPueg/video.html Ignore the craziness in the first half of the vid :)
Great video, I'll more than likely be going through this process on my old Volvo. It's mostly the bullet connectors that are falling apart.
good info.ty for sharing 😊
Good work and job.

Very good!
While trying to track down the cause of my endlessly failing fuel pumps in my AW11, I replaced the entire engine bay wiring harness. The previous owner had hacked it up. Fortunately, I found a complete harness that was in good shape at the junkyard. I pulled it out of the junker, cleaned it up, re-loomed it and put it in the MR2. Sadly, it didn't fix the fuel pump issue. That was why I was seriously considering using motorcycle carbs like you did...to eliminate the fuel injection headaches. This was around year 1999.
Thank you for your videos! I am really enjoying the memories they are triggering. :D I have even looked for used MR2s...but I have a wonderful car already, an Infiniti i30t that is paid for...which is better for me nowadays because I also remember how spinecrushing the MR2 ride was with the race suspension in it. I'm getting old... lol!
I totally understand your woes. One of the reasons why I went with carbs in my case is that my engine was a horrible mix of parts from different 4ages. I had a rwd 4age throttle body on a fwd manifold, which caused huge air leaks. I had a distributor from an ae92 (i think) where someone just soldered on the connectors to fit it, but it made all sorts of issues. The afm was always acting up. And that was just the tip of the iceberg. It was such a frankenstein that getting it running right was impossible. I also have a nice "normal" daily car, and I get you there as well. The mr2 is a weekend thing to put a smile on my face :)
Ha, I felt the need to step in and say great job, even if you are already enjoying the fruits of your labor and don't have to listen to keyboard warriors like me and others.
I really appreciate your taking the time to do a little bit of research and choosing the right process and materials (Tesa is good stuff) for the job. While your work isn't exactly mil-spec, at least you're not soldering.
Personally, I splice open wires by crimping the ends with thin copper tube, then the connection is covered with adhesive-lined heat shrink. My crimping tool is a vise grip, works fine for my motorcycle.
Someday I'll make a wiring harness from scratch using proper materials like Raychem and crimp tooling that costs hundreds of dollars, but that's a long way off for us DIY guys.
+TheFlyingHat Thank you. Glad to see someone gets the point of DIY work :)
Great work yaar
Good video - where do you get the NEW connectors from?
If you're going to crimp repair a wire in a loom use crimps that have heat shrinkable casing on them. Stops water or moisture building up in the crimp causing the wire to break later on.
+Equal Thanks for the tip. I did wrap all the crimps in high quality electrical tape to stop moisture and other materials, plus wrapped the whole harness, should be safe.
+driving 4 answers (mr2 mk1 hero) For the price of the crimps allows better peace of mind and water/moisture will always find a way to mess up your loom , but I do think you did a good job of tidying the loom up.
great job
Amazimg video!! thank you for sharing
gotcha I've seen others where they tie and tuck it so wasn't sure it that was the way u did it
My first thought when i saw the thumbnail! The least you could do is use shrink wrap type butt connectors or the heat shrink and solder in one type or good old solder and shrink wrap anything but the cheap open barrel type!
Amazing work! =D
Thank you
I use Raychem solder sleeves thay are kind of expensive but military grade and used in missiles wiring
Nice job, 👍
Basically I do the same EXCEPT I use a sheet of ply wood about 30" wide by 6 feet long laid with a sheet of paper then pin the harness down using screws and aluminum wire... draw all connectors and terminals on the paper sheet with orientation of wires in the plugs, remove all plug ends and wash them in the dishwasher, clean terminal ends and coat with electrical joint compound. Fix all frayed wires using same gauge and color wire using soldered butt splices with shrink tube, then Rewrap with harness wrap and friction tape, replacing any attaching clips and etc.
oh it looks very tangled but you are very skilled
I clean mine of all tape then throw the harness into my ultrasound cleaner
Hit it with compressed air and hair blower if I can’t hang outside in the sun
Then wrap with a great tape and put dielectric grease on all connections
Good work
Seen so many stories of frailed engine harnesses, not sure why this one didn't use wire loom but at least the effort was made to clean it up.
Nice videos I am Interested on the vehicles Waring
That cloth/ glass fibre tape works amazing.. inside a car or housing..insulating and keeps vibration noise down..example motorcycle harness exposed elements .. gets dirty, wet almost instantly and you cannot clean it..basic pvc electrical tape.. what it was designed for ?? that is why my 10, 000$ Harley Davidson didn't come with cloth tape
This is bad ass !!!
Thanks
Thanks bro! Excellent! I have 2014 Lincoln MKZ in I have to replace the wiring harness at rear( the wiring harness for rear bumper sensors, the turn light indicators on the rear bumper valence). Can you help me find the connector which the rear wiring harness connects to? It's seems that connector is missing from the bumper been damaged from accident.
Thank you.
very nice

هذا العمل جيد عاشت يدك
the fabric tape is best..wont start falling apart like electrical tape but TESA makes best tape for car audio repairs and installs for clean wiring.
thanks
Looks awesome! Great job! What type of tape did you use to wrap the wiring? Sorry if it was mentioned in the video and I missed it.
I used a product by TESA, a German brand. Its called wiring harness insulation tape and says its suitable for engine bays. Just make sure its a decent brand and that its heat resistant, i.e. engine bay suitable.
Bravo.
No, put it on the connector holder before you wrap it with tape, sometimes theirs a situations that youre going to have a tensioned wire when you put it back to the machine.
Nice bro cute wiring
Good job. But as I remember the soft tape is for interior. Under hood, you need use standard black insulating tape.
Very right. I wanted saying same thing too
so what was the heatshrink for?
i do that since 2002, and this harness was easy to repair. i use soldering iron, clips are not goods for me, maybe i do a video show how i do.
Cutting connectors is faulty idea, simple clip or pin could solve the problem.
BTW.: I worked in automotive company producing wires, we had special tools to remove wires, before that you had to unsecure connector (open blockade).
Yeah, soldered connections only other than that not bad
Bottom line is you did it! Okay now, I wouldn't have used a crimp butt connector, but they do work and even better all wrapped up. It greatly minimizes flexing. This video is years old now and I hope you have invested in connector depinning tools by now.
for me, I will just twist together both wires and put elctrical tape on it , that's it, it works for me all the time and never had experience something wrong with it.,
Beside that wrapping, some cables need special heat protection. Those were the plastic ribbed pieces. Some of the cables i have are very near to the engine, like injector wires and glow plug wires, and some areas of the harness go over the turbo between the turbo (very hot) and the heat shield. And in those areas the factory harness has all sorts of insulations of plastic, even solid plastic in weird shapes to contour the specific place on the engine. Might be reusable. And I prefer solder joints over spliced and twisted wires and heatshrink over it. But depends of the area.. a butt joint must be done with the proper tools.. i don't trust the generic ones, and the top notch butt joint crimps have a lot more protection to prevent water and air in (lots of heatshrink and silicon gel or something to fill the gaps)
I use the fabric tape and then secured them with 3M 23, and then I sleeve them using pet and then heat shrink . Yes my mechanic hates me.
Best tool for getting spade connectors out of connector is a dental pick. You can usually pick them up frorm a military surplus store. You won't know how you lived without one once you have used it! Slide the pick between the spade and the plastic, press the tab down, gently pull from the back and it will slide right out. Little harder when you have two tabs in the same block but still the best way to them out without destroying the plastic connector.
Henry Cole Stage Thanks for the tip, sounds like a good idea, I'll definitely try it next time I need to do something like this.
@@d4a There are extraction tools available for different types of connectors and terminals-

I've done this to a few harnesses. 60s chevy so simple but never did I use a but conector for a repair. if I find but connectors I remove them and solder the wire. I don't always heat shrink a single repair in a bundle can be taped then the harness wrapped I like heat shrink in situations that are not wrapped it looks cleaner.

Great video, though I solder the joins in my wiring harnesses, as the crimp connectors do work loose after a while, resulting in an intermittent issue.
If you use the proper non insulated crimps they don't work loose.
It's how the professionals do it.
And takes seconds, as apposed to the faff of soldering.
@@richardschofield2201 I prefer to solder and crimp. I am a retired professional auto engineer. Doing this the way I described gives a much more secure connection. I have been doing heavy current electrical connections this way for well over 40 years.
@@christophermarshall5765 check these guys out.
czcams.com/video/pOTrS6-mNtA/video.html
@@richardschofield2201 I never said how I did both solder & crimp. You assumed solder wicking. I AM aware of this, though I still solder & crimp. I use a combination of both techniques the guy in the video talks about, though in this video, You want some solder wicking. One other thing you failed to realise, is you took zero notice of my stated qualifications. Yes, I use expensive crimping tools, but I still solder the connections. You clearly have no idea how my system works. For this reason, plus you are still trying to make me look stupid, because you are too stupid to figure out how I do this, I am not going to explain this method. Have a good day, & do not respond, or you may not like what I have to say in my reply.
@@christophermarshall5765 sensitive little fellow.
I'm sure your work is just wonderful.
pentronix wire loom and weather pack connectors only way to go, just off from soldering shrink tape.
not sure if this was already mentioned however surgical tweezers help ease the process of removing the terminals from the connectors. alot better than those plastic tools.
or SWISS JEWELER STYLE PRECISION MICRO FORCEPS TWEEZERS SET will be perfect too.
The only thing I think might have worked a little better is to solder the broken wires and use heat shrink. Not sure what type of black tape was used but be carefull. after time with all the engine heat some black tape will become brittle and crack, split and allow moisture to seep in. good video.
+Greg Chamberlain Same here. In a few years you may got a problem with the butt connector... soldering is much safer :]
Solder is not appropriate for engine bay wiring. The act of soldering removes the flexibility of the wire in the joint area and flexibility is life, for a wire. Soldered joints are brittle and will eventually split due to the vibration ad temperature variations of the environment. Serious loom builders ONLY use crimped connectors and almost all production cars only have crimps in the engine bay
@ballsDeepMotorsports - Correct. Nothin more too say - Thumbs up
I’m trying to find those click terminal connectors. The ones that you were cutting apart with pliers. What exactly are they called?
Nice!
To all the haters, I would not EVER solder under the engine bay. Uninsulated, seamless high quality butt connectors, crimped with good Snap-On or Klein pliers, then covered with Marine grade 3:1 heatshrink made by Temco, is far superior to any solder joint. Crimps do not crack, you don't have to worry about too much solder running down the wire and making it stiff and brittle, and you don't have to worry about "cold solder joints." I have seen plenty of failed solder points in electronis, including consoles and TV's, due to heat. The soft solder alloys used in electronics / wiring are rather weak, because joints are operating at a high temperature relative to their melting point. Depending on the amount of current running through the wire, heat may or may not be an issue.
A proper crimp, forms a cold weld in which when cut through, looks like a solid piece of metal. Moisture can not penetrate, and therefore, corrosion never occurs. Once wrapped in adhesive heatshrink, the truck will rott to the ground before that joint ever fails. Crimping is also the advised option and the standard in Marine application.
Look up ABYC standards. “Solder shall not be the sole means of mechanical connection in any circuit”. Further, crimping provides a solid mechanical connection resistant to “cold joints” breaking under fatigue, and removes strain.
Lastly, in a enviroment where there will be large amounts of vibration (engine bay), solder is again, not recommended.
Crimp away driving 4 answers!
Most automotive manuals recommend not using butt joints, but state if you are going to use them to solder the connection after crimping.
Hows the tesa tape been holding up? I think the tape is for inside the vehicle use. I know theres another tesa product specifically for the engine bay. Not sure if it matters though :)
good
Dang bro they sell terminal tools, you didnt need to hurt that poor connector
