Battery cut off switch

I know this has nothing to do with the wiring, but since this thread popped back up and I think it's a cool idea, I thought I would share it here.

One of the guys on the B body forum runs a kill switch that is a push/pull switch. Rather than come through a metal panel on the car, he came through a tail light assembly. Now if he ever converts the car back to a street car, all he does is get another tail light lens. Just always thought that was a cool out of the box idea.
