The actuator contains two motors.
One to lock or unlock normally and the other to deadlock.
To unlock the unit apply power to pin 2 while earthing both pin 1 and pin 6.
Now it gets a bit tricky as the ford wiring diagram contradicts itself.
Applying power to pin 1 while earthing pin 2 should lock the unit.
Applying power to pin 6 while earthing pin 2 should double lock the unit.
As I say the diagrams are contradictory so it might be pin 6 to lock and pin 1 to double lock
