Out of all the issues my truck has had, this one drives me up a wall almost more than any of them. The rear doors will not activate the dome light. I've cleaned up the dome light contacts and they are good - they work every time with the front doors. I've pulled the switches in the door jambs of both rear doors and they both test good.
I had some electrical "issues" in the rear of the truck from a tow package install, but I chopped out the weird aftermarket epoxy-encased relay box and reconnected all the wires per the FSM. I also cleaned all the connector contacts in the rear driver's quarter area (1983 60 - all the rear electrical stuff is located behind the driver's rear quarter).
Here's a very odd piece of data: At SAS last summer, I was bored in camp one night and ripped out a resettable fuse in my engine bay that was screwed into an arbitrary location on the passenger fender well. The wiring ran from battery + to the fuse, then down along the passenger frame rail to the back where it dead-ended at the trailer connector. More tow package crap. Well, as soon as I ripped that out, the rear doors activated the dome light just enough to make it flicker once or twice when opening. The light didn't stay on, but there was SOME action. That stopped happening after about 10 minutes and hasn't ever happened again.
I've chased wires and it seems like the passenger side door wiring runs through a frame crossmember to the driver's side. I lose it there. This doesn't seem stock to me, but I could be wrong. Has this happened to anybody else? Does anyone have a familiarity with this circuit and where the wires are located?

Totally separate issue: The tailgate does not activate the cargo light. My cargo light is only a two-position switch (On-Off) and every other one I've seen is a 3-position (On-Off-Door). Did the early 60s - mine's an 83 - come with a manually operated cargo light? Maybe the two position switch is (Off-Door), but that seems odd to me.
