I saw this in response to another post about Chassis DC Fuse Panel Issues.
Though cryptic I think I saw some of what you were saying under the stop lights. I don't understand the split front to rear tho. I am looking more closely at the schematic posted in the thread. Any thoughts ?The clearance lights are powered through the headlight switch as part of the parking light circuit. I know that sounds a bit ambiguous but it's a start.The fuse would be under the dash area... Do your dash, front park and tail lights work?
EDIT: An LED license plate lamp was connected shortly before the rears stopped working. We then unhooked it and no change. I did see a schematic, I think, that indicated the license plate light is connected to the stop lamp wiring. So that is probably worth investigating furher.
