I am putting an aftermarket bluetooth set (scosche BT1000) into my new 2011 silverado ls. The wiring came with a general plug and instructions to splice in the pink to the pink mute on the stereo (am/fm/xm/single cd). I was wandering if anyone had a wiring diagram for the stereo. I hate to open the dash up for wiring that doesn't exist or match. Any help would be great.
