Well as luck would have it I had removed the bluetooth module and XM unit when I installed the pioneer ones. Hooked it back up and everything worked. I'll try jumping the BT harness so I can remove it and use the call buttons with my new deck but atleast the volume and other controls function properly now.

BTW on 2010 tourings I used a white and grey wire. Add that to the list of functioning leads.
