- -Originally a 360/C6 truck w/gauges.
-Currently has a 460/C6 and a mid 70s steering column.
-Main harness from solenoid to cab does not appear to be hacked or changed.
-There is a CD player installed in the dash, sort of, I have yet to look at the wiring.
-Aftermarket underdash A/C unit installed under dash, Sanden compressor, R-134A system.
-Original starter solenoid has been replaced before truck was purchased.
There are two wires I can't identify, both come out of the main cab harness and end near the solenoid and battery. I realize these trucks could be optioned in several ways that may not even be fully documented.
First one is what I'm guessing was originally white(looks beige now) with a black stripe. It comes out of the main cab harness and ends with a rectangular rubber block(fuseable link?). I'm assuming that it originally had a ring terminal as its length is perfect for lining up with the solenoid battery terminal. Rubber does not appear to be damaged/burnt. I'm assuming the ring terminal was either cut or broke off. There is no voltage when the truck is OFF/ON/Running.
I've looked at the various schematics here on Fordification, but I have yet to see anything that shows a white w/black wire in that location. Earlier trucks have a white with black wire for the regulator>alternator harness. Not applicable on this truck as the regulator harness uses (I not used due to gauge) Yellow(A), Green w/Red(S), and Orange(F).
Second wire is yellow. It has a 90° rubber coated female spade terminal. It looks like it would be part of the Horn relay harness plug, but the horn relay and harness are intact and functional. All three terminals are in use. This 'spare' terminal is in the same main solenoid to cab harness, this terminal ends near the horn relay. The rubber coating on one side shows it was cut off from something.
Thanks for any help in identifying these two mystery wires.
