Current side project while I wait for the Classic Industries order to fix the rear tail lights. I ordered the wiring harness from the firewall to the rear, and from the rear to each tail light. That was 2 weeks ago. Thank you coronavirus.
Also been working on installing new ground straps. Ordered a new set after this whole tail light ordeal. Found out the truck had 1 of the 4 that the shop manual shows its suppose to have. That's probably part of the tail light issue, but the harness back there was so trashed from the previous owner.. I'm glad I ordered a replacement.
