Help me find an underhood ignition wire
 

I have a pressure switch mounted in my oil pressure sending unit on the side of the block. I would like to wire into my ignition so that should I lose oil pressure my ignition will cut off. Perferably an underhood wire that I can wire in series. Can anybody give me a wire color that goes through the ignition switch? Is there one at the starter relay?

I think you would want the one that kills the ignition module ??? I would or think thats what you are asking for. The stock wires are over by the starter solinoid /coil area. I believe the colors are red and white. They are in a plastic connector. I probed mine and that was it. These red and white wires are the ones I used when hooking up my MSD ignition . Hope this get you close or there.
