I have a Rx2 that was already converted to FB alternator but neither of the wires on the back plug were connected when I got it, the battery dies all the time and the alt isnt charging at all. Where is the plug in the factory position that I can hook the R Terminal to? Im pretty sure my Voltage Regulator is already gone also.
You need key on voltage to the "R" terminal on the back of the alternator.

Thats what I pretty much figured out, Ive just gotta find out where to get a switched 12V at under the hood. I was hoping to be able to just get it from the original harness that the Voltage regulator would have plugged into.

The 81-88 alternators need a 12v to trigger the field terminal (upper male connector on the 2 wire pig tail). just tap run a wire from this point to the igniters 12-V (trace the wire from coil + to igniter +).
