[slippery1]

Hey guys,
I have the wiring schematic for my bmw car phone. I was wondering, does anyone have the wiring pin out on the bottom of the BB because if they do I may be able to splice a cable and make my own in car connection. For those of you that have a BMW, I open up my slidding door between the two seats and my BB slides in there perfect and keeps a perfect fit for it. I could mount a wire inside that door that no one will ever see and splice it to the BB cable, then my in car speakers will work and my mic will also work.
any help would be appreciated.
