2011 F150 Radio Wiring Diagram - 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.. The 12 vdc output from the generator is a last resort for charging batteries. You use that to charge the car battery if you are miles from anywhere and you ran it down running the trucks radio.
