Glenn,
That's what's referred to as a 4G board.

OK, if you are running a G203 for that axis, use the correct Wago connector to plug into the board. Your wiring *should* be as follows, mating to the factory ShopBot wiring (Motor wires to ShopBot wire):

Red to Black
Yellow to Green
Blue to White
Black to Red

If the motor goes the opposite way you want it to, just swap the Black & Green on the motor cable. Current set resistor should be set on the board for 1.5A. If you motor is a higher amperage, then you will not get full power out of it AND you will need a heatsink over 2A or so.
