Some bootleg cabinets may use this pin for coin counter power. This adapter leaves these pin unconnected.

Button and Switch Layout:

In most circumstances this adapter will work as intended with your cabinet without any modifications. Problems may occur playing some JAMMA games in a modified cabinet with less than 3 buttons, or only one coin switch present.

If the button order is wrong you may need to swap the wires going to the buttons behind the control panel. If a button doesn’t register at all, say only JAMMA button 2 and 3 work, you may need to run a jumper from button 3 to button 1 at the cabinet wire harness edge connector.

If game can’t be coined up, say in a case where only COIN2 switch is wired in the cabinet, and the game only supports the COIN1 switch, you may need to swap the coin wires on the harness or potentially jumper them together to get the game to coin up.

Rev 1.0: Initial version. Current production version.
