Hi All,



I have a bunch of 2 player 2 button US control panels with Molex connectors.



1) How do I add and wire in 3rd button for games that require 3 buttons?



2) NE1 know punchout hole size for Happ (not Sanwa) buttons. I can prbably figure this out. But if NE1 knows greatly appreciated?



I want to convert about four 2 player 2 buttons to 2 player 3 buttons.



Any Pinouts or wiring diagrams apreciated. Need the wiring info more than the punch out size.



I will attach picture within a day



Thanks

Bob Presutti

I figured out half of it.



Just need to daisy chain the ground (white wire) to one side of the 3rd button.



Was thinking about throwing in a 3 button game and then going into test mode and just pokin' aroung with the other wire until the SW3 turns on but I do not want to 'poke' the wrong pin and blow something out\.

Poke away. You shouldn't blow anything.
