Will this mess up my PCB?

I have a dynamo cab that has a Neo Geo 2 slot. Stereo sounds does not appear to work (but I do have 1 speaker going) so I can't say for sure that it is using a Neo Geo harness, it could be a bare-bones Jamma harness. The panel has 6 button holes with 4 button. If I wire up 2 more buttons to my SFIICE board using a kick harness, is it safe to just plug the board into my existing harness? I'm assuming it is since there are just a few small differences between Neo Geo and Jamma, but I didn't want to risk it before I got a second opinion.

Just to be clear, want to drop a Jamma board into a cab that has a Neo Geo board today. If the harness is Neo Geo, is there any risk of damage to the board?
 
If the cab is wired for the stereo sound that is output from the 2 slot board then you will fry the audio amplifier IC on a standard JAMMA board if you run it in that cab.

The chip will get finger blistering hot then die.
