Far left, connector going nowhere on stock non ML 07 GS350. Does anyone know?

This is in the trunk by the stock amp.

 

see if you can find the answer in this manual...

Thanks pman, that manual is legit! I have not located it yet will spend some more time thumbing through it later.

You wouldn't happen to have one of these for the steering wheel controls? My right side controls are not functioning, the DISP button and other two voice buttons.

*edit, never mind its in that manual!

 

That connector is used for a satellite radio tuner in 2007+ models.
