This was made before the days of SB proprietary electronics. Looks like Blue earth sold them the controller and the breakout.
I see a gray wire coming out of the 2-pin terminal block at the top of your photo. It appears that the other drivers show 2 yellow wires present, but the accessory drive has a gray wire going out somewhere in left field...Where is it going? Looks like it goes to the power supply for the steppers?
If you emulated the same wiring scheme as the other axes, and you plug it in & get nothing (from say the Z axis) then I would take a careful look at the driver card for the Acc and make sure that there aren't any burnt traces, 'domed' or leaky capacitors or fried diodes. Test what you can comparing the good driver boards to the Acc one.
Dumb question...but is the rainbow connector fully & correctly seated on the Acc driver? It isn't hard to set it with one pin off on one side.
I don't have a PR controller here to look at right now...
