I'm working on cleaning up the wiring to the back of my truck. I have a few wires coming out of the harness that I'm not sure what they are. There are some pics below. The first two are at the back of the truck. They aren't the sending unit connectors. The other two are near the transmission/transfer case.
Thanks!
Did ford include connectors in the wiring harness for options my truck doesn't have, such as dual tanks? Maybe that's them? I can't seem to track them down on the wiring diagrams. The 3rd picture I did resolve. It was a broken wire for the LH turn.
X2 if it is in the middle of the truck (frame) harness where it goes from the proportional valve area and then towards the rear (down the dvrs side inside of the frame rail). Then yes could be for the in cab xfer case indicator, but that AFAIK is normally a 73-76 item and not on a 79 4wd truck item. Also the lone bullet connector (if it is again in the middle of the truck frame area, can/could be for the fwd/aux side fuel tank sending unit.
I had a little time this evening to look at some of the wiring. One blue wire goes to an empty connector. The brown and white goes to a plug with the brown wire, that's got that side of the plug empty. The remaining one is hooked up but don't know what it goes to from the plug.
