Kill switch wiring diagram

Lee. Is this setup for NHRA or is it for theft deterent purposes? Isn't your battery in the trunk? Wondering where you placed your battery kill switch? This looks good. That is some serious gauge wire going to the starter. Did you buy this kit from MAD? Thanks Lee. I am interested in making a kill switch for my car but had been looking at the Flaming River setup. WOuld like to hear more about this setup.
