In this case, if the power switch had been wired to the ground, and the battery ground cable broke off the switch and dangled, there would be no complete circuit, simply ground to ground. The postive cable would be grounding out every time it hit a frame part, or fuel tank, and arcing like crazy.

MOTER, that is exactly what I planned on doing. There would be a negative cable leading to one pole on the switch, then a nother cable from the other pole to a frame grounding point.

MRJB1929- The "keep alive" wire is a small gauge wire, ( inline fused ), that would jump across the two terminals of the switch, thus completeing a circuit, even when the switch was off. The large cable from the battery, and the other going to frame ground, would be switched. The idea of this "keep alive wire" being fused is that if one tried to start the vehicle with the master switch off, the low amp fuse, (which is all that would be required for computer memory) would blow from the high amps the starter would draw. This would prevent a complete circuit of any sort so the starter wouldn't turn.

Being the switch is the keyed type, I hoped this would perhaps foil thieves, if they tried to hot wire the ignition switch. Being it would be a ground kill switch, would perhaps lessen the chance of them figuring it out quickly. A smart thief coulkd try and jump the switch posts, but they would need some heavy gauge wire in their pocket to do so..
