Help an old friend !

A friend of mine has bought a 1998 840ci sport, very good ? its not a bad car other than the faulty bits, so the immobiliser packs up and the car is recovered to a so called BMW diagnostic specialist who promptly tares the dash apart looking for a mysterious loss of voltage ???? 9 weeks past then came the call ' i don't think i can repair this' ! So says i of to Mr BMW dealer with you, so the car was recovered again and of to the dealer, who within the day had diagnosed the fault as the immobiliser module and offered a price for the repairs, the car was collected the next day reprogrammed and working. The so called specialist had only loosely fitted the dash parts so over the next few days we began to secure various plastics, switches and trims until we came across a wire from the glove box lock mech ? We refitted the lock and clipped in the micro switch but were does the wire go ??????? We then began to strip the glove box, centre console and various covers and air ducts ! but no joy, the cable from the switch is @ 30cm long so moving in an arc there is only so many places it can plug into but nothing, 5 separate people have now looked, its becoming game a sort of lottery as to who will find the connector first ?
So i need help as to were this connector goes is in relation to the wiring harness behind the glove box or centre console or somewhere any pics would be helpful also
PS i you have any sense do not and i repeat do not go to that BMW specialist on the Team Valley Trading Estate at Gateshead UK as he can not remember were it plugged into8er.org/forum/index.php?attachment/27932/

it would seem that the so called specialist ????? had when refitting the dash and surrounding areas had joined up any connectors that looked as if they were the same !!!! what a dick head !!!!!!!!!!!
so as we went through the bits and pieces it became clear a few adjustments and hay - presto things are working again.
Some BMW specialist ? I think not !
