    Help: Fuel Pump Harness Wiring Diagram

    Guest-only advertisement. Register or Log In now!
    Can anyone help me with figuring out which wires are what? This is the harness that connects to the fuel pump. It has 4 wires going to the harness to the pump. I'm figuring 2 wires (+/-) are for the level sending unit and 2 (+/-) are for the pump. Does anyone know which is which? TIA
