    IGF and IGT aren't circuits - they're labels for two pins / slots on the ECM connecting it to the igniter.

    The pin locations are apparently different on a 3RZ, depending on tranny type.

    Automatic:
    IGF = position 17
    IGT = position 23

    Manual:
    IGF = position 3
    IGT = position 20
