Ok I completed the retrofit and now have functioning rear PDC with Idrive integration.

This was probably the biggest pain in the ass retrofit I have ever done. Had I known it would have been this much of a PAIN IN THE ASS I probably wouldn't have done it as I dont like messing with the electronics of my car.

Hardest parts were definitely removing the fusebox behind the glovebox and untangling the god damn stupid Orange and green twisted wires to tap into!!!!!!!!!!!

To answer my own question above I tapped into pin 7 on x11001 on the blue connector. if you look on the rear of the glovebox after you remove it you will actually find a piece of paper which describes what each fuse behind the glovebox is for. Fuse #7 which corresponds to Pin 7 is a 5A fuse for PDC.
