This is assuming your car is still 6 volts, positive ground.

1. The 12 volt switch, even though it probably would work, is not even rated for your car, so why even consider it? Remember, 6 volt system require heavier components because of the greater amperage carried. Equivalent systems carry twice the amps as 12 volt systems.

2. I would put it on the negative (hot) side. That way all power to the car is cut off. Put it on the ground (positive), and everything still has power going to it.

3. 0 is OK, 00 is better.
