aerial wiring route
 

can anyone tell me what route the pink and white wire from the radio to the aerial conection in the boot takes.
i am trying to instal a aerial motor in my 1977 xj6c and although i have a live feed from the battery (brown wire) the pink and white wire appears to be dead.
i would like to chase back the wire without pulling apart the car to find it first
thanks

found it
