Lighting Harness
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 Last edited by Renegadevtwin; 09-27-2024 at 05:37 AM. Reason: clarification and still need a answer |

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

Re: Lighting Harness
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

Re: Lighting Harness
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.

Re: Lighting Harness
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. 22535 1968 FORWARD LAMP HARNESSK5, With Gauges $332.00 39212 1968 FORWARD LAMP HARNESS-INT REG ALT DRIVER SIDE K5, With Gauges $366.00 Note: Modified For Driver Side Mounted 1972-84 Non-Serpentine Belt ("SI" Series) Internal Regulated Alternators. 39287 1968 FORWARD LAMP HARNESS-INT REG ALT PASSENGER SIDE K5, With Gauges $381.00 Note: Modified For Passenger Side Mounted 1972-84 Non-Serpentine Belt ("SI" Series) Internal Regulated Alternators. 22530 1968 FORWARD LAMP HARNESSPickup, With Gauges $318.00 39063 1968 FORWARD LAMP HARNESS-INT REG ALT DRIVER SIDE Pickup, With Gauges $353.00 Note: Modified For Driver Side Mounted 1972-84 Non-Serpentine Belt ("SI" Series) Internal Regulated Alternators. 39211 1968 FORWARD LAMP HARNESS-INT REG ALT PASSENGER SIDE Pickup, With Gauges $366.00 Note: Modified For Passenger Side Mounted 1972-84 Non-Serpentine Belt ("SI" Series) Internal Regulated Alternators. |

Re: Lighting Harness
Talk to AAW about your situation. Below is what they offer, but a guy there a while back told me they can customize their factory replacement harnesses. You could ask them about the wire gauge and see if they think it's sufficient for your truck's lighting. But I can't imagine an upgrade to 12 gauge would cost too much, unless they have a ton of these in stock. But even then, maybe $50-$100?
This one is for factory gauges. They may also have one for warning lights. https://www.classicindustries.com/pr...s/CT21250.html Also, the one above is for an original alternator with external voltage regulator, but I'm sure they can do one for an internal regulator. Carefully read the description.

Re: Lighting Harness
I bought this one from eBay. It plugged right in to my M&H upgrade harness.
I modified it for my application but the quality was very good. It was $210 when I bought it https://www.ebay.com/itm/254800670477

Re: Lighting Harness
The main difference between 67 and 68 should be that the 68 harness has the wires for the side marker lights.
Just finding a 68 GMC headlight harness let alone a 67 is a challenge though.
