I have thought of putting each circuit on its own switch, but that's alot of individual switches. I was hoping to hit one switch to put power to the starter, interior lights, wipers/washer pump, etc. Sort of like the factory combination switch that triggers the accessorys along with the starter. But I'm not confident enough to just run the wires and see if it works, I would hate to fry my new MSD, or the new starter or set fire to the new wiring or ??
