wires that are hot when engine is running
I need a wire to draw power from to throw a relay when the engine is running.
I have a York belt driven compressor (on board air) with a magnetic clutch. I want to make it impossible to drain the battery by leaving the clutch magnetized with the engine off. Thus, I want to find an easy-to-access wire that is hot ONLY when the engine is running.
The only option I've thought of, that's easy to get to is the daytime-running-light circuit.

Only when the engine is running or only when the key is in the right most position? If it is the 2nd then if you feel like fishing a wire through the firewall you could pig tail off of the back side of the cig lighter - the main wiring harness isn't too hard to get to either. You just take off the few screws and the 10mm bolt under the steering column. You could easily find a keyed wire there.
Or were you hoping to locate one under the hood?
