How can I hook my one-wire alternator up as a three-wire alternator?
Some Powermaster one wire alternators (i.e., pn/n’s 17127, 17294, 37294, 47294, 8002, 58005) can be hooked up as a three wire …IF the vehicle is equipped with the two spade GM or aftermarket wiring harness. The Powermaster one-wire alternators have a black plug cover on the side of the alternator. This can be removed and the GM or aftermarket two-spade wiring harness can be plugged in for three-wire operation. See your alternator instruction sheet for further details.
