Not sure what you are really asking. M and S are two different signals. On the Vs., M is for one side of the Vs. board and S is for the other side. On a dual monitor Playchoice PCB, M is for one speaker S is for the other speaker.

You posted the pinout in a different post. 21 = (Main) Speaker gnd 20= (Main) Speaker positive. Y= (Second) Speaker gnd, and X= (Second) Speaker positive
What are you trying to do? The Vs board is basically two games so there is a speaker for each. The single monitor playchoice pcb only uses one speaker and the dual monitor pcb uses two speakers.
