Depends on what you are trying to accomplish. Your E34 is prewired to work with a highly sophisticated Motorola/factory phone system that is integrated with both the dash display, the OBC, and the stalk controls. But not a generic flip phone. With the VR feature (voice recognition) of the factory phone, you can even tell the phone who to dial for you:)

If all you are looking for is a power supply, here is the pinout of the 8 pin modular connector you will find under the rear center console section of your car:

1       LGnd
2       +9.5
3       TData
4       CData
5       RData
6       AGnd
7       TX - Hi
8       RX - Hi

Disregard the other connectors for the interface box, speakers, and microphone.
