MSD wiring

You can but you want a consent hot from the switch. Don’t want run or start as those circuits are not hot at the same time starting the car. Think like the radio wire, it’s hot with the key being turned on. I wired mine with a switch under the dash as theft protection…

I have to look on my car but think it is one of the wires 932,933,934 in this group.

yep......932, 933 and 934 are the ignition wires.....but do I NEED the kill switch with the key swith?
