General Wiring Question
So, I was looking to see if it had a factory trailer wiring connector that I could use and found the 3 connectors. 2 of them were identical(about 6 wires) and were below each tail light and the third was larger(about 10-12 wires) and in the center behind the spare. The thing that is new to me is that when I took the caps off, instead of the caps just being plain plastic, they had metal pins in them that actually plugged into the connectors like jumpers. All 3 were just "dead-ended" connectors, but the caps have those metal pins. What are these?
Once again I don't know if newer Fords use these(I've got an '84 F-150), but an answer will help me learn more and probably others. Thanks in advance.
When I wanted to hook up my camper shell's Hi-Mount brake light, I found a labeled wire in one of the main wiring looms under the truck bed near the rear bumper.
I would guess the pins in the cover would be there to help keep the plug ends clean. As I said at the beginning, I have no idea. Especially without wiring labels.
