For anyone who may find it useful, here is a scan of the MG-Rover drawing for the door lock, and followed buy a map of the pinout of the connectors for the lock unit ( as seen on the lock itself, not the wiring harness).
Look for a resistance of about 1 ohm on the switches (3 to 4 ohms with meter lead resistance) and between 17 and 30 ohms across the locking motors (I cant remember which was which).
