Hello, I have a 1999 XJR. Inside the roof lining at the back there is an antenna cable going down the left rear pillar and is going to the relay/fuse area in front of the rear seats. This cable has been cut and I am trying to figure out where it is hooked up to in the roof. It isn't the antenna cable from the security unit in the boot to the top of rear screen, or the antenna cable going to the radio antenna on the right rear quarter panel. Any ideas ??

 

After market cell phone ? You know those little bee sting antenna that fix on the rear screen to boost the cell phone reception whilst on the move.

 

It might be part of the sound system, from the CD changer.

 

Mine was the cell phone
