Lighting Harness - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I bought a repo engine harness from Summit.
Cannot find any front lighting harness.
Rear harness is ok.
Any leads on stock replacement lighting harness? Thanks

Thanks for all the responses
I realized now that I should have a specified why I could not find a repo lighting harness. Number one it's a GMC and number two it's a 1967.
I looked at the wiringharness.com site and the other suggestions and still nothing for a 67 gmc. I sent a email to gmc paul
Iirc the bulkhead is different on a GMC and the wiring between GMC and Chevy is different. Please advise. Thanks

Painless or American auto wire I would think be able to help. Also GMCPaul is good at knowing what is best available.

AAW:

$344

These wiring harnesses have gotten so expensive in the last couple years. I went looking for the American Autowire 22220 that you posted the picture of and said $344.... thankfully they can be had for less than that. Summit has it for ~$250

I'm not sure about the re-pop harnesses, but I think the stock harness used 14 gauge wire for high and low beams. It's a long trip from the battery and alternator through the firewall, to the light switch, and back out to the headlights. I would I highly suggest 12 gauge even with standard wattage bulbs. I've heard that M&H will do this for you.

Have had great luck with M&H!

That's is interesting. I think I would give M&H a call.

I looked in their printed catalog and they list a front light harness for a 1968 GMC. Not sure how different that would be from 1967 because I think 1967 and 1968 chevrolet are the same.
