What's the cleanest way to wire a cut off switch
I can not understand what could be better .
Well you might actually try reading the RULES
This isn't about you or what you have done. It's about the OP who wants to be able to show up at the dragstrip.
The battery must either be in a metal box vented to the outside, or a metal box / sealed battery. If not a metal box, must have a sealed all metal firewall behind the rear seat.
Switch must KILL THE ENGINE (which yours does not do)
Switch must be in the positive cable
Switch must "kill all power"
AND it must be easily accessible at the REAR of the car. A push-pull switch MUST shut off by PUSHING, and not pulling.
The reason for the double pole switch is that if you have the engine running --on a car with an alternator --and you yank your switch open, the engine will keep right on running on the alternator.
From the 2012 rulebook
