Any one know where I can find the pins outs for the "??" harness? I'm wondering if the blue tooth controls came through this harness. I want to find a way to get the steering wheel phone controls to work. Thanks

 

 

Time to get out the multimeter... That's probably going to be more easily answered on your own.

 

thats the speed sensor pin on the stock MMC nav.

 

Sorry, I meant the harness that the "??" are next to. That pic was from another post pointing out the VSS.
