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/redblack/orangered/yelloworangegreenThe replacement color wires:blackred/yellowred/tanbrown/orangeAutozone 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.
I just got it hooked up and i can hear the solenoid switching, the gauge goes from way below E when the ignition is off, to right on E when the ignition is on. When I switch tanks there is hardly movement in the needle and hovers around E, if not moving at all.I new that both tanks were almost empty, I will get some gas tomorrow.
