If you are not set on the disconnects at the CP you can always buy a fully loaded jamma harness and just wire the cabinet for mvs using it. The coin displays are on a second harness if I remember right.
You can buy an MVS harness from http://www.therealbobroberts.net/ .. Of course it doesn't have the disconnects for the control panel. I have the control panel side of the wiring, if you want to get the disconnects, but not the system :/
