Rear Lights Re-Wiring!

[SonomaComa]

I have a 1970 GMC C2500 Long bed. I am trying to replace all of the wiring from the plug on the frame near the end of the bed to all of the rear lights.

I have been shopping here..... http://www.classicindustries.com/sho...t%20Wiring&p=2

Is there any wiring difference in wiring configuration between a Chevy Panel/Suburban and a Fleetside?
Wiring for a Fleetside is $99.99. Wiring for the Chevy Panel/Suburban is $29.99 and $129.99.
And I cannot tell if it is just bare wires or it has the connections on each end for the specific light bulbs.
Has anyone else re-wired there lights and what did you use?

The Suburban wiring is very different from the truck wiring. The Suburban rear harness goes up the A pillar and back along the top of the window frames. Then down inside the back pillars to underneath the cabin. The harness also contains the fuel guage wires. It starts at a connector (8 pin I believe) that is part of the Suburban/Panel only under dash harness. I believe that $129 is the complete harness and the other ones are the individual parts. I have a 67 so I don't have any knowledge of the marker light wiring but there are several connectors that break the harness in to sub harness's

Having done this on my '70 longbed; I would recommend removing your existing entire rear light harness first; since after all you are going to need to do this step anyway whether you buy a new harness or not.

It isn't too difficult; the worst thing is having all the debris rain down on you while you unthread the harness from all of it's twists and turns; so a dust mask and safety glasses (actually goggles!) and maybe even disposable painter's coveralls will help for the removal.

I was able to salvage my existing rear light harness although I did need to re-splice and solder and cover a few areas with double layers of heat shrink where the previous owner had spliced in a trailer connector. I found quite a few bare wires around that area where over the years various trailer harnesses had been spliced in.

It was quite a bit of work cleaning and inspecting the harness and fixing the breaks though - so you might be happier to just get a new one. $100 sounds about right. Check AAW's website because their PDF price list shows all the options; it will answer your question about the Burb.

I removed and replaced all the non-adhesive wrap; you can order it by the roll from American Autowire and I think The Truck Shop and Brothers..maybe LMC Don't try and substitute the sticky stuff..

Yea, someone has spliced a trailer light connector to the rear lights and then removed and very poorly soldered it together. Then cut into it again for a two-bulb license plate light set up.
I tried to fix it but when bending the wires the insulation just cracks and breaks off. It looks like Classic Industries has alot of that stuff and it is from American Autowire.
