remote battery shut off switch

well, 1st of all. not a race car, I drive it on the streets, the lever goes though the rear bumper and is very visible, bumper off right now for other repair work. just added this, the shut off switch rod is removable and street driving for vehicle security, can't be started with no juice from battery, ....unless break into the trunk. and then rod is added so if want to go to the track.... and as for the trunk neatness, the car is being used for storage as being worked on right now. I would never have all that crap in the trunk.
