Listen to your radio after turning the key off--just like modern luxury cars. After shutting down the engine, this unit will keep the radio power active for 15 minutes or until a door is opened. This allows you to continue listening to the radio without leaving the engine running or the electric fan operating. Not limited to just the radio; could be wired to control all accessory power so you still have control of the power windows after the key is off. 

For vehicles where the door switch supplies a 12v connection (many newer cars with remote entry and ‘60s era Mustangs).
