The J3 connectors supply low voltage to the drives from the small power supply to the right of the drives.
YELLOW = +15
GREEN = common
BROWN = -15v
The plug on top of the each drive has two shielded cables going to it. One is the tachometer signal from the motor and the other is the reference signal from the CNC.
The drives were not wired with an enable signal. The high voltage power supply for the drives was turned on and off for that. SERVO RESET turns on the high voltage. E-STOP, OVERTRAVEL LIMITS and OUT. SVO-ON from the CNC will either keep it from enabling or shut it off while enabled.
The OUT. SVO-ON should come from your Pixie's enable now. The charge pump would also be wired here if used.

From the above I understand that what I was hoping the J3 connetor was about is wrong. Now I'm struggling to figure out where the wires from the Pixies need to connect. I'll re-read this a couple of hundred times, see if I can get it to sink in. I'm gonna look for something labeled OUT. SVO-ON. Then see if I can find someplace to put the Pixie ref+ and ref-.
Appreciate all your help.

Edit: I forgot to mention that I am easily confused.
Edit: So I should put ref+,ref- from the Pixie's here?-->>>"the other is the reference signal from the CNC."
