Two are one set of coils, the other two are the second set.
Take a test meter and check for continuity between two wires. Mark them as A+ and A- Check the other two and mark them as B+ and B-

Don't worry which one is which as that's configurable later in software.

Did you not get a technical document with the motors, or a wiring diagram for the motors ?

Once you have worked out what are the phases, you will then need to find what is the start and end of the phase.
you need to get the start and end of the phase right or one phase will cancel the other out and you wont get the motor moving.
If this happens then swap one of the phases around.

Missed that it was a 4 wire motor, once you have the two phases, you can just connect it up.
