[@CarsSimplified]

Excellent instructions! The one thing I would do differently is simply a minor order of operations change; leaving the built-in heat shrink on the connectors unshrunk until all the wires have been crimped in. As shown in your video, your order works just fine, I can just see myself holding the connector at a weird angle and partially shrinking the unused side by accident, potentially forcing myself to start again. I imagine you can get more shrinking done with less lighter fluid that way, too. Again, great instructions! Hopefully this ends up being what people come across when they're looking to learn how to do this!

[@802Garage]

Def a great idea! I ended up doing things in a bit of an awkward order for the sake of demonstration. I'm still not sure my favorite way to do everything. Appreciate the comment! 😁

[@madalynmonroe6441]

I love how u Take your time to respond to everyone's questions and comments. It's very appreciative and you're video is very informative. Could my headlight being put back in the wrong way and not being locked into place be the cause of the connector melting? What is it just a very strong coincidence? This is why I always want to do everything myself. Because when other people do things and stuff gets messed up. I can't help but feel like it's something they did....

[@802Garage]

Thanks very much! It is possible that your headlight not being assembled or installed correctly caused the connector to burn up. It really depends on the style of bulb and assembly. If it was able to knock around and the connector came partially loose or if the connector was not fully installed, it could cause excess heat. This is because if the connector contacts are not fully mated, the current has to go through a smaller area which will add resistance and create heat. This can cycle into thermal breakdown. It's also possible something shorted causing the melt. I always advocate learning how to DIY as long as you are comfortable trying and do you research! If you post a pic to Instagram or something I could take a closer look. Could very well be coincidence, but most likely if a new headlight was installed and the connector burned up, something wasn't done quite right. Could be that the connector was forced and it actually bent a contact for example.

Not bad! Personally I would’ve soldered but you did a good job with those connecters… One thing I would recommend though is some dielectric grease on the connecter before you plug it in, that’ll save it corroding up.

[@802Garage]

Not a fan of solder in vehicles, but I know the debate will rage on. ;) Dielectric grease def a good idea. Thanks!

[@The_R-n-I_Guy]

When possible, I pull the pins out of the connector and swap them to the new one. I work at a collision repair/body shop and I deal with this quite often. I don't like splicing wires unless I have to. Especially since newer vehicles have extremely thin wires and if you try to splice them the computer won't receive the correct voltage and can cause problems. Sometimes it works, but if you splice wires on a newer vehicle and it still doesn't work. That might be your problem

[@802Garage]

Great tip! Yeah CAN bus wires are especially finnicky. I have another video to edit about making new connectors from scratch which will include installing pins. I'll try to make a tutorial on what you recommended in the future too. In this case of course, the pins themselves were totally destroyed. Avoiding splices always best, but making sure the splice is waterproof is next best I'd think. :D

What if the connector has 2 wires while your car only has one? The part from the auto stores and everywhere online it has 2 wires, seems plug with one wire doesn't exist for some reason. Will it still work if I connect just one wire on the connector?

[@802Garage]

If it is the same connector and it clicks together then yes. It's just a single wire in a two wire connector. If it's a different connector entirely then it's just not as common and you'd have to find the right one, or you can replace both sides. If you need more help, tell me what connector it is on what car.

[@rachelcavally7637]

does it matter which color of wire goes first? Should i disconnect battery first? i have red, blue, and black wires on the old connector and new one which helps but im not sure if theres a certain order to do them in

[@802Garage]

It is always a good idea to disconnect the battery when working on anything electrical. Just unhook the ground connector and make sure it is tucked away from the battery terminals. In truth, as long as the key is off, it would be hard to mess anything up here. Still best practice! It does not matter which order you splice the wires in as long as the correct wires are spliced.

[@johnwieliczko6195]

A couple additions from someone whose been around the block a time or two... 1. There is a butt splice that has solder in-between the wires inside the heat shrinkable butt splice. 2. Something to remember when splicing multiple wires for a single connector is to stagger them. Make each splice about an inch away from the nearest splice. This’ll save you if the heat shrink ever wears down (causing a short) and will make the harness slimmer and closer to factory since you’re not cramming 3 butt splices next to one another. These were probably some ocd things on my part, as the method shown obviously works, but they are tips nonetheless.

[@802Garage]

Thought I replied to this. Maybe it didn't go through. Yes the solder seal connectors work as well. For most applications I'd just boil it down to preference. Agreed on the staggering, especially if you need the harness to fit in a tight space. Thanks!

On our 2003 Chevy Cavalier the burned socket has 3 wires: Black in the middle, Red and Green (Green is burned) on the sides. A new socket I bought has 3 wires - all Black. Does it matter which one goes on Red which one on Green, if I connect central Black wires together? Thank you for so useful and informative film.

[@802Garage]

Yes it matters. Generally you have to connect the wires in the same order they were before! So you must connect black from your harness to the middle black on the new socket, green to whichever side green was on in the original socket, and same for red. Hopefully that makes sense.

[@Jacob-rt6on]

Is there a reason you dont solder wires instead of crimping? I have a pigtail to attach and i keep seeing videos with crimp tools are they better than soldering?

[@802Garage]

The quick answer is for automotive applications, yes. Soldering has more room for error and the issues are less obvious. The two main problems are cold joints or inadequate solder and too much solder or hard brittle joints. With a correctly sized crimp and the correct crimping tool, such as what I showed in this video, it's much easier to get it right. Even this isn't professional level crimping, but the heat shrink butt connectors add water proofing and strain relief, ensuring the repair will last longer. With soldering you need heat shrink and silicone paste or glue lined heat shrink to accomplish similar protection. Hope that makes sense. If you look up crimping vs soldering for cars there are a lot of good videos out there by big names like High Performance Academy and Haltech. Wiring is a deep rabbit hole, but worth going down to get informed.

Hi there, I changed my light twice and each time it works for only 1-2 minutes (bulb isn't burnt however, but connector socket seems melted on one side, how could that happen?). I think now nothing works and I have to change the connector, what could cuase the overheating ? At 1:42 you mention blowing fuses does that mean light bulbs ? Thanks

[@802Garage]

I would guess the issue is with your connector, but I can't be 100% sure. If you had a wiring issue like a short, it would blow the fuse for your headlights, located in the fuse box in your engine bay. That's what I was talking about when I mentioned a fuse. Technically, a headlight bulb works similar to a fuse, but obviously it is not supposed to blow, it is supposed to glow. I would examine the connector itself for any discoloration, especially black or dark brown spots on the connector, on the wiring, or on the contacts. The contacts should ideally be shiny metal and not corroded or burned looking. You can also smell the connector and if it smells like burning plastic or wiring, that's generally a bad sign. Check the wire leading to the connector for any brakes or damage or hot spots as well. The other main reason your bulbs could be blowing so quickly is if there is a ton of moisture in the headlight housing, but usually they would have to directly touch the water for it to be an issue. Since you aren't blowing a fuse, and it seems you only have the issue on one side of the car, I would say the connector is the likely culprit, but again I can't be certain.

[@miguelh4750]

@@miguelh4750 It's definitely possible moisture is the culprit if they pressure washed the car. There's nothing wrong with pressure washing, but it might have exposed a problem that already existed like cracked wiring or a bad headlight seal. Best of luck.

Nice video. However, I could not use it. Because my wires are different colors. All your wires were the same. That would make it easy. Lol. But thank you. I still give this video I thumbs up..

[@802Garage]

I'm sorry it wasn't more helpful for you. The only adjustment you have to make when your new connector has different colored wires, is you have to make sure you match the wires based on where they lead to in the connector. For example, if it's a three terminal connector, and the first terminal has a red wire on the original connector, but your new connector has a blue wire on the first terminal, you have to connect the blue wire on the new connector to the red wire on the car's harness. Match each wire to the corresponding wire based on position rather than color. Hope this helps.

[@derrallblackmon6705]

Thank you very much. Very detailed and articulate

[@ZanesFacebook]

I have a friend who likes to buy cars with, uhh, "problems," especially electrical problems. I've noticed that vehicles built 2012 or later, regardless of manufacturer, tend to melt the low beam headlight connectors. Here's a quick, TEMPORARY solution - remove the burnt plugs from the headlights, and run some speaker wire from the fog lights to the low beam bulbs. You will lose the "auto on" ability for your headlights, since the low beams will now be switched on and off by the fog light button. Also, if your low beams aren't working, and the connectors are melted... If you just sand down the contact points with some 80 grit sand paper, and maybe hit the contacts on the bulb as well, you'll be good to go for a couple weeks. If your plugs look melted, hit them with some sand paper first - I promise you that they'll work again. Long enough for you to replace the plug end.

@@TeamGun Any connection adds resistance. A bad solder job will add far more. Wiring repair and motorsports wiring professionals in general will almost always recommend crimping over soldering.

@@TeamGun Every. Single. Automotive wiring repair expert I know in the industry disagrees with you. Period. Soldering CAN of course be done properly and be effective and reliable. It simply is not the preferred method for automotive wiring repair, nor is it suitable for novice repair jobs because the margin for error is too large. If a crimp adds more resistance than a solder joint, the crimp was done incorrectly. If a solder joint is cold or inadequate, it will also add resistance. It might not even be measurable on a typical multimeter, but every splice and connection adds resistance. You will never introduce anywhere near an Ohm of resistance with a crimp or solder joint unless it is done completely wrong. People crimp injector adapters all the time. "Did you know solder is NEVER used in a professional motorsport wiring harness? Did you know that a properly executed crimp joint is actually stronger than the base wire?" www.hpacademy.com/technical-articles/solder-vs-crimping/ One of numerous sources I can provide you.

You can’t be crimping connections like that. If you don’t want to test things yourself it doesn’t matter, feel free to believe what you want. I don’t agree, and I can post articles arguing against it as well but I won’t because I’ve tested this myself. You can test it yourself if you want. For shit like lights, yeah it won’t matter, but some stuff it does.

@@TeamGun Dude, I'm just telling you I have done said testing. There is also an entire industry of experts who know everything I said. You are grossly exaggerating how much resistance any properly done crimp will add. I'm not going to argue what is settled knowledge. I can provide you with unlimited sources if you'd like. I get it that you have always done it a certain way and you're gonna keep doing it, but saying that soldering is superior or not to use crimps is simply wrong. There are no current articles by professionals which disagree with me. I have tested plenty. Watch these videos and learn something. As they say, a good solder joint is better than a bad crimp. A good crimp is better than a bad solder joint. If both are good, a crimp is ALWAYS preferred for automotive applications unless specific constraints require soldering. Again, this is especially true for professional style open barrel crimps, but used correctly the crimps in my video are just as effective and will not add significant resistance. Certainly less than the actual harness connectors themselves. I am aware that proper solder joints can add less resistance than crimping, but the amount is so incredibly small as to yes, be negligible, for all automotive applications, which is why crimping is still preferred. Looping back to your original comment, it is also of course perfectly adequate for the purpose in my video. kzbin.info/www/bejne/e3LVY61sp6yJbdE kzbin.info/www/bejne/nJKvn2CJn7uZrbs kzbin.info/www/bejne/poC3o4ZsYtKBqqM kzbin.info/www/bejne/e5DQaaucaNuZj6c

Missing your videos, bud.

Thanks it means a lot! I'm actually going to try to work on the first part of the rotary BRZ swap tonight. So look out for that soon.

Hi 👋

Hiii Stella!

I've seen worse from professionals. Nothing you did was horrible and the repair looks like it will serve well for years. Things to think about are... FIRST Extract info from the old harness before cutting it off. It may not work but it isn't without informational value. Note pin position and color of wiring at pin location for performing the repair. If you need to pass a harness through an opening the harness cuts should be at different lengths to avoid bulking up the harness with three crimps at the same position. Shrinking should be done for all insulated butt connectors at the same time to reduce time spent on that step by picking up and putting down tools over and over.

All great tips! Agree with everything. In this case I was targeting people who will buy an aftermarket flying lead connector or connector with pigtail harness attached. I should have mentioned making sure you match up the correct wires more though. I have another tutorial to edit which shows how to make a connector with flying leads from scratch. I hammer home pin and wire position more in that one. This repair style is definitely targeted at the amateur and DIY crowd. Just intended to be leagues better than a bad solder job with electrical tape or a hardware store butt connector left to trap water and corrode to heck, hahaha. Thanks again!

Barrow connected are garbage solder it back You’ll thank me later

Never had a single one of these fail. What's important is using decent quality crimps and the proper crimpers. Most people are not good enough at soldering to make reliable connections for automotive applications. Professional wiring outfits in general almost never use solder on vehicles unless absolutely necessary such as to boards, with extremely limited wire length, or in potted connectors..
