Which harness
I have a 1967 C10 Stepside with a 350ci motor that I am in the process of rebuilding (very slowly). When I shipped it over from the States to the UK there was a large infestation of tin worm that has had to be dealt with before I could even think about using it, well am about half way through all the welding and just have the passenger side of the cab to do.
The wiring on the truck was lets say very poor, some owners over the years had done their bit others hadn't, it was an electrical fire waiting to happen. So I have ripped out the entire harness from front to back. I have attached a couple of photos one of the state of some of the connections and the other is what I cut out from under the dash. The speaker wire was used to power the solenoids for the door poppers. ![]() My question is, after looking at harness for the truck on line, which one is best and are there any out there that I should be avoided and why. If anyone has any recommendation could you please put a link to the harness that would be a great help. |

Re: Which harness
I used American Auto Wire for my truck. It was extremely comprehensive and easy to install. I'd highly recommend them. It is great having turn signals and tail lights that work!

Re: Which harness
x2 on AAW. I've used them as well and have nothing but good things to say about them. M&H is another good company. I also used a Painless harness about 15 years ago and it was good as well.

Re: Which harness
M&H is the gold standard for replacement wire harness. Most professional restorers that care about originality and are looking for concourse certification use M&H. They are exact as original equipment manufacturer. Every wire is correct gauge, color and have the proper ends. They are truly plug and play.

Re: Which harness
^ this. If you want factory plug n play, M&H is the way to go. If you want the ability to customize and add additional circuits, AAW is it. Both owners of these companies were in business together at one point.

Re: Which harness

Re: Which harness
The link above is to the AAW classic update. There is a couple things you should know before you use it. They have a nice web site and you can read the install literature before you purchase. Anyhow, you will lose the external voltage regulator and the ammeter. It's not a stock harness, but it is a fun and easy rewire. It's a classic update - not upgrade(not sure anything is better). When I got mine the only issue was the headlight switch. They said there was only one manufacturer making them. I had to get a second one sent. I just recently swapped the old switch out. If you want easy, I don't think it can get any easier! Just check all your grounding. Get the crimper, a good wire stripper, heat shrink and I did a fair amount of soldering. I decided on loom tape and I used split loom in some areas below the dash and some areas in the engine compartment. You have options, pretty big after market for these trucks. Do whatever works for you. Have fun!

Re: Which harness
The truck at the moment doesnt have s wire connected as it is just about completely striped. So yes i am after a complete harness, but not a stock one as i have to add stuff such as, door poppers, electric fans, fuel pump and msd etc. All of the lights are being converted to l.e.d. and the front headlights will be on there own circuit to take the load off of the headlight switch. I would also like if possible to run the wires under the hood behind the fender just to tidy everything up a bit.

Re: Which harness
I also used the American auto wire kit 1970 c10. My first time doing a job like this and it was surprisingly very easy to install! I would definitely recommend this kit.

Re: Which harness
I just rewired my whole truck using this kit: 10206 - CLASSIC-PLUS CUSTOMIZABLE GM PICKUP TRUCK CHASSIS HARNESS (1967-1972)
https://buypainless.com/products/10206 I'm a noob and was able to get a hang of it, all wires are labeled and color coded. It has everything you need for stock and gives you a lot of upgrading options supposedly. Not cheap, but worth the investment in my opinion. |

Re: Which harness
I haven't sourced my LED's yet but most likely I will get them off of eBay or similar, unless I put another large order into LMC \ Brothers etc but that is doubtful.
