BobA -
Thanks for the pic. I think I have it, but just to clarify....
I leave all 11 wires from the JAMMA harness connected to the Power Supply. Then I will take the power wires from the JROCK unit and connect it to any one of the +5V wires/connectors on the JAMMA harness. Is this right?
If so, can I just splice into one of the wires, or should I add it into the actual harness? Also, would it just be easier to connect the JROCK unit directly to the Power Supply?
Thanks alot for your help.
