While installing a Double Din radio in my 2000 Boxster, I discovered an unused 4 pin connector just laying there between the shifter and the lowest bay in the radio stack. I would like to implement it if possible but I can't find it on any of the schematics. Here are the colors:
Pin 1 - Brown
Pin 2 - Yellow / Black
Pin 3 - Green / Black
Pin 4 - Red / Green
I have attached a pic...any help is appreciated.
