Well, I'm not familiar with that very board but it should be the same as other Midway (and Williams) PCBs of the early 90's, which means that beside the main board you have a separate board for sound. You need to connect the two boards with a cable for data and another for power and among the voltages required by the sound board is also the infamous -5v, which not all superguns can supply. Also, if I'm not mistaken, there is no built-in volume regulator: you have to get a pot the right size (5K?) and wire it yourself to the appropriate connector on the sound board. And lastly, you need an additional harness for 2 of the 5 buttons (for each player)...

it's standard jamma and needs -5V.

it does have volume controls, they're in the test menu.. no external ones.

There is a very clear wiring scheme in one of the last pages of the pdf...
