As far as I know there is not a wiring diagram, but you should be able to work out the wiring with the pin outs. (from Sarge77's Link)

The things highlighted above in
RED are connections you will probably not need to make. The Books, Test, and Payout Sw (
gold) might be worth finding a space for if you have spare switches inside your game - its up to you.
From there, its finding a spot for the buttons (
blue) on your JAMMA harness. The JAMMA standard gives you eight buttons - one start and three action (A/B/C) for each player. You could easily use the following:
Player 1 "A" = Start
Player 1 "B" = Bet
Player 1 "C" = Take Score
Player 2 "A" = Double Up
Player 2 "B" = Big
Player 2 "C" = Small
You could also use the Player 1 "Start" button and the Player 2 "Start" button for something like this:
Player 1 "START" = Start
Player 2 "START" = Bet
Player 1 "A" = Take Score
Player 1 "B" = Double Up
Player 2 "A" = Big
Player 2 "B" = Small
Those are just 2 options - you could come up with several more on your own.
It really comes down to are you wanting to use your JAMMA game to test you PCB or make a fully functioning Cherry Master. The problem is that JAMMA does not support lighted buttons (
purple). If you are going to use lighted buttons, it would be safest to avoid placing those on the JAMMA adaptor - especially if you want to keep the joysticks for other games. You do not want to accidently put a steady 5V into one of your JAMMA games if you wire the lighted buttons to say where the joysticks are on a JAMMA harness - you could fry something.
EDIT - just looked at your adaptor pic and it does not even have the wires for the lighted buttons so nevermind.
If you need the JAMMA pinout:

(except he calls the Player 1/2 Action Buttons "Button 1" "Button 2" and "Button 3" whereas I said "A" "B" and "C")
