Stepper Motor

I have reached the point where I am starting to fiddle with a stepper motor and controller.  The stepper motor has four inputs.  The controller has six outputs, of which two are DC- and DC+.  It appears that the four conductor cable from the motor goes on the four connectors that are not DC- or DC+.

There are 2 pin DC cables on Amazon that would be seem to fit except that I do nor think there is room to fit the 4 pin connector there as well.  There must be a six pin connector that connects the motor cable and a two pin DC connector.   Any ideas?
