I have a stepper motor ( Model = 23KM-K381-01V , NO.T6Z23-07 , DWG NO.56AA80112).

**Motor Specifications:** 

Motor is unipolar , 6Wires , 2A current , 1.8 deg step angle.. 
Motor is second hand.
I do not have datasheet of the motor.
and the worst thing is no wire is connected to the motor. so I can not take benefit of color coding.

So my question is how do I know that which wire of the motor should be connected to A+ , A- , B+ , B- of the stepper motor driver...

Thanks in advance for the help.
