P30 should be treated as if there were 3 wires; ignore the black wire.
No Sega XY cabinets I've seen have 4 wires per connector; only 3 per
connector is needed. I believe the wiring for the control board pinouts
above should be reversed, but before I say anything else, I'd like to
consult with my lawyer first.

Oh, BTW, no, I've never seen any of these connector ever have plugs in
them (although in retrospect, that probably would have been a smart thing
for Sega to do). This is because some have the pins clipped from the
board, and some do not.

I'll double check my setup tonight, but if you can't wait that long, feel
free to cross all sorts of wires and fry your XY set (because then I can
sell you a set! MUUUAAAAHHH!)
