Assuming this is a CS-130D,
Pin D is voltage sense usually goes to battery.
Pin C is field control goes to PCM so PCM can control alt output. (C2/11)
Pin B is lamp control. On stock setup is goes to PCM (C2/77)
If you're running it non-PCM controlled can just use pin B to the lamp. If not using a lamp put a resistor inline to switched +12; 560 ohm 1/2 watt will do the trick.
