Bob,

You said, "You can put it just about anywhere you want, but you have surmised correctly to put it on the ground circuit. It is less sensitive to amperage draw and won't require as much concern for cable size. "

I think your wrong with stating that it is less sensitive to amperage draw, unless you are placing the switch other than in line with the main ground lead from the battery.

I always thought that the switch was to totally disconnect the battery from the cars electrical circuits. In this regard, it would make no difference if the switch was placed in either the positive or negative lead of the battery. The only concern would be to have a switch rated to handle the starter motor current demands, which are very demanding.

OR..... maybe I'm wrong in my thinking here. Are the switches only killing the engine, in which case they only have to disconnect the ignition circuits? Still effective for safety and theft deterent.
