My MSD instructions state I can add a kill switch by grounding one of the wires (the white one). I’d like to add a series of switches (probably 3) off the wire so that they all need to be switched in order to start the vehicle. The instructions say the wire needs to be grounded. Can you add a series of switches and still ground all the switches so that it would work? I’m real bad with electrical stuff, so any feedback/drawings, etc would be helpful
