What harness do I need for a G23 for the MEI cashflow? I've been told that it was a JCM iVizion installed previously and only some of the wires were hooked up. It was just the frame, no head/transport or cash can. I took out the iVizion frame and put in the MEI frame upside down, everything seems to line up correctly even though the bill head is upside down, will that work like that? I hooked up what would fit but I'm lost and afraid to power it up until I know for sure I did it right but it doesn't look right to me and just want to make sure.
