V · 07-25-2012, 11:08 AM

I need to figure out a way to run a pump from a power source that only has voltage when the engine is running.

Are there any sources that I could tap and use a relay to do what I need?

Last resort I think would be to make a circuit that get power from an IGN source then uses a pulse activation relay that will turn on when key hits "run" and stays on until IGN is turned off.
