Exactly! The first thing any manual tells you before starting most work on a vehicle is. remove the ground (negative) cable from the battery. It makes sense to me that my switch wired this way, will function as I desire it to.

Now my engine is EFI, has a computer, and electric fuel pump, so I'm thinking that in an emergency situation, IE; smoke, fire, sparks, or accident, I should turn off the ignition switch, then turn off the battery switch. Engine is off, Fuel pump is off, any shorts will stop immediately.. makes sense to me. Oh and perhaps I should add grab fire extinguisher..lol

Denny, now see what you started...
