I have searched around trying to find a wiring diagram for the fuel delivery system. I have a 1985 Ford E150 with dual gas tanks. I have a Chilton Ford Pick-Up and Bronco 1976-1986 but the wiring diagram for the 1985 F150 does not match the color wires for the plug at the fuel tank switch.
I have a replacement switch that was produced by Ford (Motorcraft switch E6UB-9A050-AB) and the wire connector plug (Ford D9AB-14489-JD) to be spliced into the existing wire harness coming out from the center of the dashboard.
OK, here is my problem. The stock wiring connector has 5 wires going into the stock switch. The stock switch also has offset terminals so it will only go on one way.
My replacement switch has 6 symmetrical terminals. The replacement wire connector has 4 wires coming out of the back of the connector switch to be spliced into the existing wiring and two of the wires double back to other terminals for a total of 6.
The stock color wires are:
green/red
black/orange
red/yellow
orange
green
The replacement color wires:
black
red/yellow
red/tan
brown/orange
Autozone lists a switch for my year that have 6 screw connections (SW48) but I wouldn’t know how to wire that switch to my stock wiring, or what terminals doubled-back to another terminal.
Urgh!!!! I hope that I explained my problem with enough information. Thanks guys.
