Sorry Patrick,
I am not the electrical guru that you are. I need you to dumb this down a bit. 12v light? Are we still talking about a test light, or something like this

My small red wire goes directly from the MSD box to the IGN terminal of my ignition switch. there is also a green wire going to the same IGN terminal of my switch. Is that what you are maybe thinking goes to the front of the car?
I have never stripped the wire in the middle of a run. Is there a proper way to do this? When I am done testing, do you just wrap the stripped part with electrical tape or cut it and butt splice it?
