Has anyone hooked up a remote disconnect switch per NHRA rules in their car for mounting the battery in the hatch? Specifically I know I can run the wiring from the remote battery through a disconnect but the switch will not shut down the motor once it's running. I'm thinking one of the disconnect switches with a auxillary contact running a secondary relay to disconnect the power to the electronics.
