okay, I placed my order with Summit. I went with 1-guage cable, and the summit 250-amp waterproof switch.

My MSD is fed directly off the starter relay. If I'm thinking this through correctly, when you hit the disconnect switch at the back of the car with my ignition wired like this, it should shut the car down, correct?




UNLESS you have the alt out put wire is attached to
that same lug on the relay, then the ignition will
still be hot... if your alt wire goes to the battery
side of the master it will kill the engine
