I have a 2017 Spark. I recently discovered that the electric power socket (AKA the cigarette lighter socket) is connected via the ignition switch. Thus no power is available when the car is not running. I have a need to have a continuous electric power source when the car is not running. This would be used to run small electronic devices. The current draw would be about 200 milliamps. I have been unable to find any wiring schematics.
Can anybody suggest an simple way to connect to the electrical system to accomplish this. I suspect that there is a unused terminal at one of its fuse boxe
