I'm hoping you can you give us a bit more info.

Are you trying to avoid the vehicle starting as a theft deterrent only, or did you want to use this in a racing environment to shut down the engine, or entire vehicle, in an emergency while it is running?

As Mike asked, knowing exactly what the "kill switch" is supposed to do is critical to installing, and wiring, it correctly - on that, if it's for Motorsport, you need to know EXACTLY what the regulations demand, as they are NOT all the same for different series, or governing motorsport bodies.
