 Bill, I hadn't thought of going that route -- too simple and obvious an approach, perhaps.

The +12 volts to operate the solenoid could come from the spare blade connector of the battery junction on the positive battery cable.  Then, disconnect the factory white-red wire at the starter solenoid, and connect the solenoid's terminal to your added switch.  The other end of the solenoid's coil is grounded through its case, not a terminal on the end, so you won't need to add a ground wire.  The big copper strap carries +12 volts to the starter motor when the solenoid is energized.  The terminal with the white-slate wire provides +12 volts to the ballast resistor when the solenoid is energized, thus bypassing the ballast during cranking.

This arrangement avoids cutting any factory wiring, and allows an easy return to the original setup if you, or some future owner, should ever wish to do so.
