Help with Fuel gauge not working slash faulty wiring around tank

[DesertBen44]

Hey guys, haven't had much time to come on here or play with the ford lately, been getting almost 24hrs overtime a week, Finally getting to some issues I should have addressed long ago...

Anyhow, my front tank gauge has not worked since I got the truck, I know it could be the sending unit in the tank, but the wiring on a solenoid looking item on the front drivers side corner of the bed concerns me, pictured here

I am wondering what wires were supposed to go where, so i can figure this mess out before purchasing any expensive parts. In my haynes/chiltons manual i cant find what this is or what it does...


If anyone can take a picture of there setup that would be great, so i can try and correct this.

Another thing that would be helpful is any pictures of how the wiring should be on the trailer/reverse/taillights, as mine is modified, imagine how impressed I was to look under there and find this.

i know the pictures suck but that's how they decided to connect all there wiring, loose, bouncing around, and twisted together with no insulation...

I know what to hook up to what, just wondering how the wiring is routed from the factory, if its in a plastic conduit, etc.



Thanks in advance!

On a 92 there should be seven wires going to the rear for trailer hookup. Black-Red-Yellow-Brown-Blue-Green-White. From the looks of things, one of those colors goes thru a 12V self resetting circuit breaker then thru the solenoid, the solenoid does not have the signal (S) wire hooked so it isn't doing anything. You would have to trace the wire off the circuit breaker to up front to see what it may have been, more than likely to a battery.

White--Ground
Blue----Trailer Brakes
Brown--Trailer running lights
Red----Left turn and Brake light
Green--Right turn and Brake light
Black---Trailer battery charge. Could be an Orange wire.
Yellow--Any aux. use or Backup lights on trailer.
