It is explained in the link I posted.

You normally want resistance test not continuity but it does depend on your meter and exactly what you are trying to do.
Well I have found the two pairs of pins that show resistance, on my new motor. I will pull off my old motor and check that also.

My main question is the wiring. Do the two pairs or A and B have to be wired to a matching A and B from the old motor? Like A to A and B to B or can I swap them around?
