When I hook up my cd player where do I hook the battery up to. I have a yellow wire coming from my cd player which is the memory wire, and the red wire coming from the cd player is the main power. I know that the black is ground. The only problem is where do I hook the red and yellow wires. From my truck I have a white wire (do not know what it is for) an orange wire(battery), and a red and yellow wire. Does anyone know how to hook the cd player up????
