Hi

I have a wrestlefest cabinet and wanted to add a TMNT jamma to it. When I did only player one gets credit. coin doors 1-4 all give player one credit. Player 3/4 have diffwerent pins than wrestlefest so I ordered those harnesses online. I would think player 2 should work though. It seems strange that all quarter slots credit player one. Can this be fixed with wiring or is it not possible to play tmnt in this cabinet. I am very new to arcades and assumed jamma switching was as easy as plugging in different boards.
