    Howdy!

    Trying to correctly wire a South African built "Custom Defender" that is most assuredly not NAS. A/C unit that came with the truck wasn't up to Texas heat. Start poking around, thermostatic switch is bad, Freon leak and poor draining of condensation. Both leaks are fixed, new thermostatic switch, sensor and module in hand.

    (Full disclosure - I work for an Indy, have been given this information from a Tech. My actual knowledge or experience is neither expressed nor implied)

    So here is what I hope to find (parts included for reference)

    I need a pinout (with wire colors) for the connector at the thermostatic control unit

    P/N JFC101990 on HVAC schematic for 1993 RR Classic component [Z102]


    I have the switch (P/N PLX663) [X183}
    the temp probe (P/N JTF100280) [X101]
    and the controller (P/N JFC101990) [Z102]

    Thanks in advance
