That looks like the connector to my radio head unit. If so, 8-10 are definitely not what that above diagram describes. On mine, there are three brown wires there, which I believe all run to ground inside the dash. The other end of the cable is apparantly grounded through a different path.

thanks guys~~~~~~~~ (97 E420 w/ Bose Amp)

The diagram is PERFECT!!!!!!!!!!!!!!! (thanks JCE)

The connector from the my pic is C-slot 10-pin connector.

Matt L; can you help me describe what you think they are? (w/ your system? seems I have 8-9-10 brown wire)

Looks just like mine. I think they run to ground, but did not actually look to see where. They run separately from the rest of wires on that plug, which presumably end up at the trunk. Mine's a '96 210, with Bose sound.

Are you trying to attach something to this connector, other than the MB CD player? If so, I'd like to know if it's possible. I'm betting it's not.
