I recently bought a APC 12 volt, volt meter (product #107402). I am unsure as to how to install the volt meter so that it shuts off when I shut the ignition off and it turns on when the car is turned on. The instructions were limited and unclear. I would like to know what to hook the wires up to and how to find them.[/align]

 

Run it off your your heater fuse or something and run the light off your head light fuse so the back light will turn on when you turn your headlights on.
