I have a 88 460 transplanted into a 82 jeep j10 with a 4 pole solenoid and a single heavy gauge cable running down to the stock starter. I would like to upgrade to the hi torque starter but it take an additional lighter gauge wire to function. Does anyone know what terminal on the fender mounted solenoid I should use? I assume I need to bring a circuit that is open and closed by the ignition switch?

 

The wire from the ignition switch on the original solenoid is the red/blue wire that goes to the "s" terminal.

INFO here

The "S" wire is not a good source to energize the new style starter due to a much higher current draw require by the newer starter solenoid
You should use the original Ford starter solenoid to power the new PMGR starter solenoid.
Move the main power supply wire for the starter to the battery side of the solenoid.
