Your motor has 2 coils inside, these are called (for example) coils 1 and coil 2. Each coil has 2 ends, these are called A and B so you have 4 connections, call them 1A 1B 2A 2B. That is the standard notation that everyone uses for a 4 wire motor.
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?

So I installed the new motor and it is extremely loud and it runs really warm. So warm that it melted some of the nylon standoffs.
I lubed all the guide rods and tightened all my screws and am still getting a really loud motor/printer. Now I am looking to purchase another motor and found the following website:

Am I looking to purchase a unipolar or bipolar motor?

- If your motors getting toasty you may not have the right voltage stepper. I would test the motor driver with your multimeter and see what the driving voltage is and make sure the motor is rated to handle it.
Examples of different Nema 17 Steppers:
3.4V Stepper
12V Stepper
24V Stepper
*PS: These are just examples of the different Nema 17 style motors, I have no experiences with these sellers.
