new tail light harness
 

I haven't easily found anywhere to get a new tail light harness. anyone have any info? Mine has had trailer wiring spliced into it and Id like to just get a new whole harness.
With that being said, where does it plug into the front of the truck at? Wheres the next junction up from the tail lights?

American Autowire and M&H Electric Fabricators both offer rear lamp harnesses for 1977 GM trucks. There are various options depending on your truck's wheelbase and bed type.

The rear light wiring is in 2 sections. There is an intermediate harness that runs from the bulkhead connector on the driver side of the firewall, down along the frame, and ends in a connector near the rearmost frame cross member. From there, the rear lamp harness contains the wiring that runs to the individual lights.

awesome, thank you sir
Now to decide which one to use, M&H is a lot cheaper.
