Quoted from PinballTilt:Mine doesn't match the picture above, my ground and +28 volt are bridged. Orange makes sense for +28, but don't I need a ground?
Yours doesn't match because yours is correct. Orange isn't 28 volts, the Red wires are 28 volts. The Orange wire has 28 volts when the relay is energized, otherwise the Brown wire has 28 volts when the relay is not energized. The ground to operate the relay comes from Q-7 on the CPU board.
