Are you installing this with your factory head unit. You did not specify. If you are, you can splice the remote wire into the ACC wire on the back of you head unit, or you can splice into the power wire for the cigarette lighter/ power outlet.

If you are connecting the remote wire to an aftermarket head unit, the wire is usually blue with a white stripe.
