Reserving this for the weekend. I found a couple connections in the engine bay that needed cleaning and just started the drivers side tail. Removed tape/untwisted/scotchbrite clean/solder and shrink wrap/new ends. Got to about the 3rd wire and upon closer inspection the other wires were completely corroded. I carefully used a razor blade and unsheathed them as far back as I could and the wires were black throughout.
Still no driver turns/brake and reverse lights.
