Use a multimeter to check continuity of the A, A- and also the B, B- pairs just to make sure you have identified them correctly. It is important that the pairs are correct but it does not matter how you connect the polarity to the controller. If a motor subsequently runs in the wrong direction this can be corrected by changing the Direction Low Active signal in the Mach3 Ports & Pins / Motor Outputs settings.
