The honda/acura wiring harness doesn't have a blue/white (amp turn-on) wire. Which wire on the wiring harness do u guys use to connect your amp turn on wire? my Sony XPLOD hu was installed free when I bought it. When I tried to connect the amp wire ( have a Xplod amp that's running a single 10' bandpass) I noticedthat the head units blue/white wire was connected to the honda/acura wiring harness blue wire. Again which wire should I connect my amp turn-on wire 2. The head unit has a sub control that I'm dying to use.
