Just curious if anyone knows what the (3) smaller plugs are that plug into the 2006 BMW X3 Main Radio Harness plug.. There is only space for 2 to plug in currently there is a black one and a white one plugged in and the 3rd is tapped to the main harness and has a tag on it that says CD-CHS or something like that. I am fixing to install a Pioneer DEH-P8400BH and bought the scosche kit with harness and the PAC SWI-RC adapter to maintain my steering wheel controls. Just trying to cross T’s and Dot I’s. making sure I have all I need or if there is anything else I need to know. anyone?
