Important: This adapter does not support the -5V power rail which is not present in Jaleco cabinets’ wiring harness. Games that require -5V may not run.

Button and Switch Layout:

In most circumstances this adapter will work as intended with your cabinet without any modifications. Problems may occur in a modified cabinet, or with games that require more than 2 buttons, or 2 coin switches present.

If the button order is wrong you may need to swap the wires going to the buttons behind the control panel. Similarly, games that require a certain coin switch to be activated to coin up the game, may not work until the coin switches are either bridged or swapped.
