How do you replace antenna on 86 Jaguar XJ6?

hope this can help a little.i had to replace my attena motor in my 92 xj6.and to do that i had to remove the rear light casing in the boot to be able to remove the carpet to get to the motor.then its a case of unplugging the wires undoing the motor casing. you can now access the attena. bearing in mind my version is newer so it may not be the same.(92 xj6)
