There is no ground or positive with these. You just have to try hooking them up to check for the roation you want.

When you have the left and right pair in front of you with the output shafts facing each other (power connections are to you) if you connect positive to the right side of both motor and negitive on the left side both motors, they will spin in the same direction. This is what I learned for using our motors.
