Do you own a multi meter and can you measure resistance?
Connect up one lead of the meter one wire. Find the other one that has a low resistance. That's one coil. Check that the other two they are the other coil.
You now have identified the two coils. One is A the other is B.
Now hook them up to the A and B terminal.
Jog it. If the direction is wrong reverse one pair of coil wires. Direction should change.
Take note of this on the other 2 motors.
Repeat on the other small motor.
Set current using resistor as noted in manual.
