Repeat for the other leg, paying attention to the original polarity of the opto in relation to the board. Now when the gun is dropped and the PC board shifts around inside the gun shell, the opto can also shift and not break off.

Games like CarnEvil, Johnny Nero, and Sports Shooting/Ranger Mission where the gun has half a mile of wiring and a dozen connections/aux boards, the +5v can get pretty low by the time it reaches the gun board. Cutting out some of the excess connections for the +5v can help significantly with gun tracking on these games (if your +5v inside the gun is low). I won’t go into details here — If you’re comfortable working on games, you can probably figure out how to run an extra wire from the power supply to the gun :)
