Range rover 2003 transfer in neutral help please

Hi, this is a long shot so dont give me negative if no joy.
on the p38 they suffer from a bad electronic selector.
now, i do not have a clue what gear box or transfer you have.
any way if you look at your transfer, beside where the prop comes out, is ther like a window wiper motor with 6 wires.
if so they get stuck, rust or dirt etc.
have you checked your fuses, alos i would add. again not sure on your model.
in the fuse box there is a blank fuse, when inserted it shifts it to neutral.
the dealers wont tell you where it is.
have you put any fuses in etc, i did this 5 year ago, a p38 was jump started, leads wrong way.
i got a call as the aa did not want to help anymore. aa had a hand full of fuses out, i stuck in were contacts were. after new ecu had no drive.
you are sure its not a gearbox fault, get back to me if not sure, i can tell you how to test this.
