Right Joy-Con 2 Back Cover Installation

Align the rumble motor connector to its socket on the bottom edge of the board, and push down until it's fully seated to connect it.

Use an opening pick to press and hold the release button.

Place the back cover over the controller body so the release button cutout is slightly below the release button.

Press and slide the back cover up until the cut-out for the release button is aligned with the button itself.

Remove the opening pick.

Install the two screws on the right edge of the controller:

One 3.1 mm‑long tri-point Y00 black screw

One 3.0 mm‑long JIS 00 silver screw

Align the clips on the plastic strip with their cut-outs on the right edge of the controller body.

Insert the clips on the bottom edge first, then insert the rest so the plastic strip sits flush.

Use a tri-point Y00 driver to install the two 3.1 mm‑long black screws on the left edge of the controller.
