Hey everyone, I've got a question. Hopefully someone has a simple answer - i like simple. Without going into details, I need to add a circuit that is active the entire time the vehicle is turned off. My only requirement is that turning the vehicle off and/or removing the key from the ignition must complete the circuit! What I'm doing would draw diminutive amperage, so battery life is not an issue. Car alarms work off the battery when the vehicle is off, so I know this is possible. How can this be done?
