I think some confusion comes from the fact that many “race” starter wiring techniques are different from factory Chrysler wiring techniques.
A lot of race cars use a Ford style starter solenoid, regardless of starter manufacturer. This allows a single, electrically “dead” heavy cable down to the starter. They do this for safety, and to minimize the required wiring to initiate the starter. To use this system, you simply make a small jumper wire that connects the large terminal on the starter to the small terminal on the starter. The large cable on the starter goes to the remote mounted solenoid into a place of your choosing.
