    Default Circuit Open Relay(COR) Part number 85910-12080 question

    Howdy,

    I got a COR for fuel pump, Part number 85910-12080, it has 5 pins, but connector has 2 wires coming out of 12V IGN and 2 wires coming out of Fuel pump 12V






    NOTE - Engine / ECU in question is 1UZFE LS400 motor in RN85R 2WD Hilux Conversion, not 4AGE

    Didn't even notice until unsheathed the wires
    Never seen plug like this, spose to be from AE101?
    Do I still run with usual wiring instructions?

    White/Black - Wires to STA - Starter/ECU Start Signal. X
    EDIT: White/Black is earth
    Black - Wires to body earth - Wire to closest earth point.
    EDIT: Black is to STA
    White/Red - Wires to EFI Relay - +12v Ignition Switched power (Run through a suitably sized fuse, 10A is usually fine, but depends on your fuel pump).

    Green - Wires to engine run signal - "FC" pin on ECU. Or if you are running an AFM engine, this wire should connect to the AFM.
    EDIT: IF Motor is AFM / MAF and ECU has FC pin, wire Green to FC Pin

    Blue/Black - Wire to fuel pump positive - Gives power to your fuel pump.

    Cant find a thing on goggle or search.
    Also, Why 2 wires from these pins?
