I like this idea. If you were trying to use the cigarette lighter, you could disconnect the positive lead from the back of the lighter socket and run a wire from the coil negative post to where you disconnected the wire. When you push the lighter in, the car won't start. Pull it out to start it. I've never done this before, so I ask you guys, is it safe to do this on all types of ignition systems? Will grounding the coil do any damage?
