My son purchased a JVC KD-R950BT head unit for his'08 Focus S coupe, along with the appropriate wire harness. When he's attached everything he gets no power at all. Someone told him the '08 is different in that the wiring doesn't work as usual, you have to run a wire straight from the battery and fuse box in order to get power, but now it doesn't shut off with the ignition. Someone out there that's installed an aftermarket system have the same problem? Is there a way to shut it off with the ignition? I know the basics but this seems a little beyond my expertise. Any help would be appreciated. Thanks.
