I bought a 4 wire stepper motor & tb6560 driver board from ebay, and it arrived with the stepper motor shaft sticking thru the install. c.d. I looked up the stepper motor and found that the green and black wires go to 1 coil and the red and blue wires go to the other. I need help figureing out where they go on the board. Specifically on the a, a-,b,b- The model # on the stepper motor is 57bygh56-401a 1.8 fh no;10.11.10 I'm a total elec noob so any help would be great . thanks
