Hello was working on replacing the antenna mast and when we removed back wall carpet panels we discover a wire coming from the driver side in the upper corner that was not connected to anything. Does anyone know the purpose of the wire and where it should be connected? Below is a picture. The car is a 1997 xk8 convertible.

 

Here is another pic it looks like a pin connection. Maybe some sort of audio connection

 

Ancient radio telephone?????????
