Tiny g and wiring x-carve motors

Hello all, I purchased my c-carve without the controller so I could use my Tiny_G. The motors that came with the x-carve have green, black, red and white wires. Am I right in assuming green - black and red-white are pairs? Also, is the A1 green, A2 black, B1 red and B2 white?

Thanks

to find the correct pair for step motors.
when you find the correct pair they motor is hard to turn.

Yes, with all wires unconnected turn the shaft of the motor by hand.
Connect two wires and turn the shaft again - if the torque is higher then you have one pair and the other two are the 2nd pair. If the torque is the same (spin easily) then you have one wire from each coil, pair them with the other two.
