For the life of me, I can’t determine with certainty what wire is what and I’m asking to prevent frying the unit.

    I believe (but looking to confirm) the following:

    IG = red wire
    N = White wire
    F = Green wire
    E = Yellow wire
    L = Black wire
    B = Blue wire

    IG N F
    — — —
    — — —
    E L B

    And when looking at a 1982 wiring schematic, do both the IG and E go to ground/earth? Asking because earlier years (1980) did not ground the IG via a condenser...so I’m confused.

    u do understand that the primary color wires on the 54040 regulator side are simply the Tracer stripe wire colors on the harness side

    so solid yellow = white with a yellow tracer stripe


    hope that helps ..........

    But to my original problem: I’m building a wiring harness from scratch because the old one was bastardized by PO and doesn’t match specs (or anything close...it had a ford four pin VR). So I’m having to recreate the wheel.

    I need to determine what color wire corresponds to what function: IG N E F B and N.

    alot of this depends on what alternator u are running ?

    do u have a factory EWD , Both USA & NON-USA


    The big Tan Chassis Body FSM has some great diagrams that cover both applications #36044 & #36044E

    Do U have a 30a AMP meter cluster
    or
    A 50a AMP meter cluster

    u should have a 50A AMP on a FJ43L-KC 1982

    I’m not sure honestly. It came with the charging indicator light next to the parking brake. I’m planning on wiring it to US specs as near as I can. My alternator is a 30amp.

    New wire harness - Red wire w/ black tracer stripe : Interior Illumination




    your old FJ43 harness had a solid green wire feeding the Cluster illumination ( most likley )

    I was referring to your instrument cluster , regarding the AMP meter inside it

    Woke up to a hijacked thread. To get us back on track, I am asking the original question in another way:

    I have the voltage regulator in this picture (borrowed from another thread) I am creating a new wire harness because old one didn’t exist and I’m starting from scratch. Help me identify the wires coming out

    red wire = what?
    White wire = what?
    Green wire = what?
    Yellow wire = what?
    Black wire = what?
    Blue wire = what?

    They are what of the following choices?

    IG N F
    — — —
    — — —
    E L B

    To answer any other questions, I have a 50 amp alternator and instrument cluster. The alternator has E F N and B connectors with an external voltage regulator pictured. D6C2530F-6E1B-4615-AE6B-B9AB507371E9.png 0481F0FA-45A2-44D3-BF34-1C40C4FE92B9.jpeg

    Thank you. You can direct message me with questions not related to the above.
