You say " the truck starts."
and " I've tested the lights and they do work."
I'm not sure what you are trying to fix.
If it werks,
why not just leave a sleeping dog lye, no?
If you need more help let me know I have a 77 van should be the same harness.
And a 76 and a 78 truck, I could get ya some pic's or ask for specifics and I can have a look see.
