Does anyone have the pinouts for the non-audio wires in the X9331connector? I used the speaker lines (pins 2,3,4,5,6,7,8,10) to insall a new amp + speakers, and I want to confirm I didn’t muck any of the other lines. There are 4 pins I haven’t yet found in a wiring diagram:

Pin 1 (brown wire): I think this is a ground
Pin 9 (brown/white): ??
Pin 11 (white): ??
Pin 12 (brown): ??

Thanks for your help!
