And I didn't even submit a proposal...

Hi all!

I want to wire an oil pressure gauge in my Disco. The gauge I bought has an audible warning signal that will sound if the pressure drops below a certain level that you program into it.

I don't want to tap on a normal switched circuit because I don't want my gauge to buzz if the key is on accessories, or if it's on run but the engine is not running. So I need a circuit that's energized only when the engine is actually running, and preferably a circuit that's inside the passenger compartment.

Any ideas?
