Kill switch MS43

Need to run internal and external kill switches for a track car. I have the battery cut out sorted but need a way to kill the engine. I'm considering using a relay to cut power to the ignition at pin 1 of the X6954 connector. Comments? Alternatives?

Why don't you connect the alternator and battery together directly? This way you switch the whole car and don't have to run charging current from the alternator to the battery over your switch the whole time.

Regarding your question, yes that will instantly kill ignition.

I'm using a Tyco high current relay as an isolator. It simplifies wiring.
