Does anyone know where the speaker + and speaker - pins are for a Jump Bug?

It appears there are 2 different version of the board and 18 pin and 22 pin.
My board is the 22 pin... I cant find a pinout that shows the sp + and sp - for my board.
Can anyone help?
 
sound

pin 18 is sound out and then use pin 21 for speaker common.

cool game!
 
So I am facing this issue right now with my jump bug. When making a Jamma adapter, does speaker + go to 18 and Speaker - to 21 (or ground)?
 
If your board is the 22 pin, then yes, according to the above. Speaker+(audio signal) to pin 18, Speaker- to pin 21(Ground).

I'm not sure what is up, but I still can't get sound. I have a Jamma adapter, and according to it, pin 21 is going to ground on the Jamma side and V is going to speaker + on the Jamma side. Still no sound. Does something need to be hooked to speaker - of the Jamma side?
 
OK, I got my sound working, and to cut down on confusion, Pin 18 is Speaker + and Pin 21 is Speaker -. Most online pinouts leave the sound out of the diagram completely, or mention 'audio out' and 'common ground' for those 2 pins. No idea why it was so difficult for someone to just type: Pin 18 is Speaker + and Pin 21 is Speaker -. Cuz that's what it is. Hope this saves someone some hassle down the line.

Jump Bug, Sega (G-04-JB) <-- Not sure why this says Sega, this is the Rockola version. The game was made originally by SNK.  Did Sega distribute in Japan?
