Anyone know what that is for, its down by the fuse panel, or is it an after market mod?

A picture would help.
The E has NO A/V wires that are OEM that I know of.
Maybe it was an aftermarket stereo the someone else had
installed, and they didn't remove that wire????

Im just guessing without seeing it.

That looks to be a microphone jack for the factory security system,it's used to detect glass breakage.
