You're probably looking at it backwards. "A" and "B" are the only two terminals next to each other in one corner of the plug. There's one of those two pins missing in all the other three corners.

If the idle speed motor is working normally, you shouldn't have to do anything. The same part is used on Chrysler engines, and in the rare event one fails, you just pop a new one in and you're done. The Engine Computer controls it as necessary.
