Ok, about to wire up the VR board. Seems pretty straightforward
I know where to mount it, and am going to use SPR3 and SPR4 on the main board (Pin 5 and 6 on the DB37) to run over to the VR board, in addition to +5v and gnd.
Only question is where to send out1 to and where the pad is located on the V3.0 board to hook it up. After I figure that out, i'll hook up my desktop VSS to pin 5&6 on the jimstim and test. Once I confirm it works, I have two more wires down on my PnP harness.
EDIT: I think i'll wire it to JS10
