Hello Roger & Dave,
The info that you have posted Dave is for the P38 not the L322. The L322 doesn't have a becm under the seat.
Have you tried adaption of the transfer box Roger?
You can get info from the Topix landrover site for the model you require here http://topix.landrover.jlrext.com/topix/vehicle/index;jsessionid=47C9BB3327871D88FDB4875D99879773.prs72903
You will have to register if you aren't already registered.
Regards, Andrew
