I have an ‘08 H3 with the Monsoon stereo and OnStar (which has been disabled). I’ve installed a Kenwood DDX393 and would like to use the microphone wiring (I’m going to replace the mic, I just don’t feel like running any wires and the location is good). So I’m wondering if anyone knows what colour wires I need to splice into, and where they’re located.

 

good question! im curious too!
