I DO NOT SELL THESE. We were talking about some recent incidents involving Vintage cars and Hot Rods. 2 were stuck throttle, 1 was electrical fire. All would have less or No damage had the electrical system been interrupted immediately. This switch needs to be near you. Under the hood if you are working on live wiring, or changing electrical parts, and within SLAPPING distance of the driver. I know you have reflexes like Bill Bagshaw(Red Light Bandit) or the Late Ronnie Sox, however, electricity is quicker. You cannot get out of car, run to trunk, find keys, open trunk and twist kill switch fast enough. You can slap this kill switch in very little time. IF you are gonna run 2(1 under hood and 1 beside driver) they MUST be wired in series in the Negative cable between Battery and wherever the ground cable mounts. $25 U.S.
if you kill ground it will only stop electrical fires right? will killing ground kill engine? good idea,i have a disconnect under hood ,but that would sure work faster!
