I labeled that top right switch “Left” which corresponds to GPIO Pin 7. Continue the same process
for each direction and replace the bottom cover with the four screws along the outer edge.
Once you have the orientation, unscrew the red ball from the top of the joystick handle, and
remove the black washer as well. Unscrew the top metal plate, and feed the joystick from under
the box lid. Secure the joystick by screwing the metal plate on top of the box. You’ll want to mark
where those holes are and pre-cut a hole for each screw as well. Replace the black washer, and
replace the red ball.
Wiring
You may have noticed some 6" strands of wire and 20 female quick disconnects. You will need a
pair of crimpers or there may be a crimp tool on your wire strippers already. You will build two
wiring harnesses for ground. One wiring harness will have five quick disconnects daisy chained
together for the buttons, and the other will have four quick disconnects daisy chained together for
each ground pin in the joystick. Then nine individual wiring harness for each button and direction
on the joystick. The ground on the button switches are the lone tabs on the long side of the switch.
The same goes for the joystick.
Single wiring harness with female end. You need nine of these.
