This is a Peripheral (now PAC Audio) PPH8590 handsfree integration harness for use with select BMW vehicles.  Use this harness with a Peripheral MSS switching relay to integrate a bluetooth or phone handsfree system into your vehicle.  This harness (with an MSS relay) is similar in function and applications to the Nicestuff 68035 harness.  I also have MSS relay switches for sale in my booth.

Some of the compatible vehicles include;

1985-1991 BMW E30 3-series

1990-1998 BMW E36 3-series Business RDS or Satellite Nav

On activation of the Mute line, the audio will switchover to the handsfree kit.

You can also use this harness to integrate audio into your car stereo from other mono sources by triggering the mute enable line (navigation units, radar detectors, CB radios, etc.).  A carkit-specific adapter harness may be required for your installation (I have some of these in my booth), or the connections can be made individually.  Available on the connection to the carkit is:

VBATT - constant +12V power supply

Ground - chassis ground

Ignition - switched +12V signal

Mute - active-low trigger Mute connection

Speaker (+) - differential mono audio signal from the carkit or device

Speaker (-) - differential mono audio signal from the carkit or device
