mlaw Posted March 6, 2010 Report Share Posted March 6, 2010 This might explaine it clearer, its what i posted on an old thread a while ago. The cable for the +12v supply is already in place, as the factory head unit connects to it. I think the colour cable is white, pin 16, see notes below. You would need to connect this to a +12v supply on the new headunit. I used the automatic ariel lead which i think is usually the blue lead. By doing this it also means that when u turn off the stereo the amp is no longer powered, so u wont drain the battery when not using the stereo. You could connect it to a +12v switched ignition feed from the stereo wiring loom also. Hope that helps.
