P38 V8 4.6 gems IACV Wiring

[Oldopels]

I’ve changed the square brick plenum to a classic slopy top type and consequently now have a different stepper motor.

I need to modify the wiring from the rectangular plug to a square plug but don’t know which wires go where!

This is the current plug and wiring - the plug is marked A, B, C & D;

And this is the socket on the classic type stepper motor I’ve now fitted;

So the the question is which is A, B, C & D on this square socket?

Thanks in advance for your help 😁

Thanks Brian. 
 

All wired up and it’s settled down nicely.
