When wiring a Sanwa joystick, the red lettering on the joystick harness should be facing down towards the bottom of the fightstick.
When wiring a Seimitsu joystick, the red lettering on the harness should be facing up towards the top panel of the joystick.
In both cases the pcb should be flipped so that the 5 pin connection is closest to the buttons.
