Good Evening. I am new to this Forum and could use a little help. My old liquid cooled FD620 finally bit the dust, so I got a newer air cooled TH620 motor. The Old Gator has 3 main electrical plugs from the main harness to the motor harness. The new motor has 1 electrical plug which has 1x red, 1x green & 1x black wire. Does anyone know how to wire this new motor plug into the old harness? Many Thanks in advance.
