I was very skeptical about purchasing this, but honestly this was the best investment I’ve made for my project car, after going through the factory and old circuits and obsolete devices, I wiped the slate clean and purchased this harness. Every wire is labeled, some are printed pretty lightly but your still Able to see it. Every circuit works perfect and was pinned correctly, the factory gm connector to the column was perfect and easy to pin, the light wiring all works perfectly and as should, headlights/high beams/parking/blinkers/brake light You will need to use heavier duty flashers! The ones supplied are junk, made for like 2 incandescent bulbs, upgrade to better ones I ended up cutting out many older circuits and ones I don’t have such as power windows/locks/carb, and all the original engine sensor inputs since I’m Using a stand alone, I have a separate fan and fuel pump relays, but overall this harness is awesome, wires are all very thick gauge, and way longer than needed which is great. If your building a project car especially ls into any 80s car, this is the only route I suggest you go, it will save you more time this way than dealing with the factory body harness, it’s not 100% plug and play and you do need knowledge of automotive electrical, but if you know what you are doing, it’s a breeze. I was originally going to go with the painless or American auto wiring for $499! But I was going to cut some out anyway, I would recommend this harness 10000%

I purchased this wiring harness for my 1976 Chevrolet C10 Truck. I've re-wired a few vehicles before, including a Nova and a Chevelle. This was also not my first time using a universal wiring harness. It can be daunting at first, but there are plenty of resources (videos) out there to help. The first step was to organize the various groups (e.g., engine compartment, interior, rear of vehicle, etc.). The instructions were decent, but I ended up cobbling together some other companies' instructions for their respective universal wiring harnesses to clarify some things. If you take it slow and stay organized, this can be an excellent value over a more expensive plug-and-play wiring harness. All of my wires were clearly labeled and easy to read. Every circuit was also correctly installed in the fuse box so I didn't have to do any troubleshooting. Since my truck lacks several of the options included with the kit, I had some leftover wires/circuits that I tucked away in case I added something in the future. I'd highly recommend this kit to anyone, but if it's your first time wiring, it may feel overwhelming. I enjoy taking my time and organizing my wire routing while using period-correct terminals (56 series). Some cloth tape also makes everything look nice and protects the wires. All-in-all, a great value if you're willing to put in the work on your end!

Great harness, only thing is, the electric fan wiring diagram is missing and there’s a few unlabeled wires and black wires that aren’t labeled, I can’t find where to contact the vendor for additional information.

The quality of the components is just OK. Useable but not great. There were manufacturing errors in the fuse box that had to be corrected. The documentation is awful and does not include a complete wiring diagram. You really need to be very knowledgeable about auto wiring to figure this out. Each wire is stamped with extremely tiny and very faint labels about its purpose. You will need a good light, strong magnifying glass, and a great deal of patience to find and read these labels. Save your sanity and pay the extra money for a Painless Wiring kit instead! Their documentation is vastly better!!! Edit: More incorrect circuits were found in the fuse block! I absolutely cannot recommend this product. I have reduced my rating to the lowest allowed.

My harness did not come labeled, Amazon agreed to send another one. Same thing, no labeled wires. Would like for the seller to reach out to me. Has not responded to my requests. Harness itself is great quality, it has all of the proper connections and wire length.

THE FIRST TWO OF THESE KITS I INSTALLED WERE GREAT. THE THIRD KIT I'M WORKING ON NOW IS VERY HARD TO READ DUE TO SMEARD INK OR LIGHT INK. SAD.

I read reviews before purchasing and was skeptical at first, but once product arrived and starting installing in my 32 Plymouth it was apparent that this is well worth the price compared to name brand products, I can see where some mention that the instructions could be a little better but I have worked on cars for many years and if you don't have an understanding of electrical components and controls then you shouldn't be attempting to take on a job this size unless your willing to research, understand and learn. Very happy with my purchase great product all circuits work as they should and wire leads are plenty long enough for complete rewire of my hotrod.
