Jim the alt wire is only hot when the engine is running (switch is on).
The ign./ key goes to the small term. correct?
Where do you mount the relay? that is a good idea.

Not in the case of a 1 wire GM alternator. It will be hot all the time when connected to the battery side of the switch. If you connect the wire from the alternator to the car side of the switch, the car will keep running on alternator even when the kill switch is off. The wiring diagram kill's power power to the alternator when the switch is off.
