Small Stepper Motor

Trying to get this motor to work with a L293D Motor Drive Shield  the shield is capable of handling 600mA per coil, this motor according to the data here takes 400mA (presumable per coil) so should be good there. However the data sheet here does not relay explain the pin outs only coil A and coil B but not which wires are which coil, the truth t
