Installing Pioneer Super Tuner IIID XM ready tomorrow. I have both wiring harnesses, 1 for the head unit, and the harness adaptor for GM. Problem is this 3 wires on the GM harness adaptor are not connected, nothing to connect them to, dimmer, illumination and amp turn on; on the stereo harness the blue wire is not connected to anything. What should I do? I know that I have to find a power source else where such as the wipers, ect....
Not really sure why I have a total of 4 wires that are not connected.

the amp turn on is just for if you have a system and need a remote power supply, as for the other two i've never had my dimmer or anything hooked up on my head unit and it lit up, just didnt dim with the factory lights
