Right Joy-Con 2 Board Installation

Lower the board's flat side into the controller at an angle.

Use a spudger to bend the joystick's ribbon cable so it's perpendicular with the joystick.

Lower the board so the joystick's ribbon cable routes through the joystick cut-out in the board. Ensure the board is sitting underneath the locking tab on the frame.

Push the board towards the controller's inner edge (the side with the shoulder buttons) to prevent it from colliding with the joystick module.

Lower the board into the frame.

Use your finger or the flat end of a spudger to press the black tape onto the back of the joystick module.

Use a JIS 00 driver to install the five 3.1 mm‑long black screws securing the board to the controller.

Make sure the locking flap is flipped up on the joystick cable ZIF connector.

Insert the joystick ribbon cable into its ZIF connector until it's fully seated.

Use your finger or a spudger to flip the locking flap down to secure the cable.

Make sure the locking flap is flipped up on the Joy-Con connector cable ZIF connector.

Insert the Joy-Con connector ribbon cable into its ZIF connector until it's fully seated.

Use your finger or a spudger to flip the locking flap down to secure the cable.

Repeat this procedure for the shoulder button ZIF connector. The cable is fully seated when its brown "wings" are in their slots on both sides of the connector.
