XJ8 1999 VDP Security Antenna Connection
 

My Security Antenna on rear glass, the module or connector is not connected to the glass. Should it be. The Key FOBS are not working when put into Program Mode and now car is also not going into Program Mode when did before using headlight flash, but the FOBS do not activate. Is the antenna related to this and if needs to be connected how can this be reconnected.
Thanks
