The brown, eight-pin connector would normally be used for speaker
connections in a passive speaker installation.  If your car is equipped
with Bose, or a standard setup with separate amplifier, the brown
connector will be unused.  In some situations, it may be used to drive a
single auxiliary speaker for use by the phone kit or navigation system.

Hi Pete,
 Sorry to bother you again,but the terminal i refer to is a single
connecter,and protrudes from the back of the unit about an innch.
