re: what is a good "switched 12V" source in a car?Posted by TigerWise on 2/8/11 at 2:30 pm to LSUAlum2001
If you want to make it really easy go buy a wire harness from a shop has if you were going to put in an aftermarket radio. Plug the aftermarket harness into the factory radio harness in the car. Since the aftermarket harness has all the wires labeled you can easly trace the wire back to the factory radio's side and just tap into the switched wire. Then just return the wire harness when done.
