There appears to be more than one circuit for the starter. Which setup you have would be the big question.

There are wiring diagrams on the PAC site for the 40 Super and Custom senior cars. I'm assuming one of those would be correct for your car. Using that diagram in conjunction with the voltage regulator schematic listed for seniors & shown in the SM, it would appear to be a grounding starter switch circuit. The junior cars use a different solenoid and on those the starter switch gets power from ign switch and would activate the solenoid with voltage.

It's unfortunate the diagrams are not a bit better but as near as I can follow, on Seniors it appears the small relay which activates the solenoid gets power right at the solenoid from the battery terminal. Whether that is internal or a short jumper, I can't tell. A black wire then goes from the solenoid to the starter button. The other black wire from button goes to the aux terminal T on the voltage regulator. Internal in the voltage regulator is a set of normally closed contacts that connect T to ground. When the engine is not running, pushing the starter button will ground the solenoid. As soon as engine starts and generator brings in the cut out relay, the contacts open preventing the starter from operating again as long as the generator is charging and cut out relay is active.

If that is the type setup you have I can understand how the remote switch would work it. You are just paralleling the starter switch and going to ground directly with your switch. If you have the junior setup then I'm at as much loss as you.
