Wiring is identical as it's a JAMMA cabinet.

The wiring on multi-slot cabs is different from JAMMA cabs. Sometimes referred to as MVS. Notable differences are the rearrangement of service and test switches along with the replacement of balanced mono to stereo sound. Speaker impedance matching becomes an issue. Plugging in a 1-slot or any other JAMMA board in an MVS wired cab will fry the audio amp. Short story, 1-slots are not plug and play in multi-slot cab.

I'm not certain you'd damage a 1-slot or JAMMA board in an MVS cab. I've seen an MV-1C board play fine in a 2-slot, and an MV-1F play fine in mono mode on a Neo Candy 29 wired in stereo. Having said that, it would be better to have something like the JNX v1.2 Big Red Adapter for optimal sound quality and compatibility. Check your cabinet's speaker wiring to be sure.

Outside of frying the audio amp, the rest of the board would work "fine" outside of the aforementioned switches. The main reason why the JNX adapter exists is for impedance matching to prevent said frying of the audio amp. A friend of mine didn't heed my warning about JAMMA boards in an MVS wired cab until he burnt his hand on the blazing hot audio amp swapping boards after playing the game. He begrudgingly bought the JNX adapter and the problem went away. BTW, the audio amp frying isn't an instantaneous process, it's more like a medium to slow bleed.
