I'm in the process of replacing the pos conertone with a decent stereo, and noticed what looks like a un-connected ground wire following an antenna cable up into the roof.
It is the bare braided wire in the photo below. When I removed the concertone it was just hanging there, not attached to anything.
Ignore the attached white lead, I put that on the end to extend it so that once I figure out if it needs to be connected to something, I have the additional run to do so.
Does anyone know what purpose it serves, and where, if anywhere, it should be attached?
