Yeah ive got one, here

I want to also be able to get this to work with my mame cabinet, i take it the wires that supply the power are run from the Coin mech to the credit broad and finally to the multi power supply that i removed right? Would these be a red wire and a Black wire? Can i connect the +12 V wire (red?) and Ground (black) wire from the credit broad to my PCs +12V & GND wires, and then it will all work?
I have noticed that from the credit broad, a red & black wire runs to a analog counter just inside the coin door, would these also be the Live (+12v) and GND wires?
