Does anyone know of an engine running signal in the rear of the LR4? I'm assuming there's one either for the rear A/C or one of the computers back there. I've got a secondary battery and DC/DC converter, and have been using the switched 12V lighter socket back there as the charging trigger - but every time you open the driver's door at camp it switches back on, draining the vehicle battery. I'm hoping to find a source that only has 12V when the engine itself is running.
