Hi drummachine, If you have a later model the wire is the antenna for your remote lock.

It's more than the antenna as it's coded to the keyfob and alarm because if you swapped the inerior mirror for a different one the remote locking stops working.

What's Inside

The mirror contains the receiver for the remote locking system, which decodes the signal, and sends an output to the security module to lock/unlock the doors and boot lid.

The antenna is just a piece of flexible cable (about 0.5 mm cross section) coiled inside the mirror housing.

If fitted (usually when the mirror is fitted on an on E46) it would also include wiring for the rain-sensitive wiper sensor, and auto-dimming rear mirror.
