Instructions
Move the Wii Remote wrist strap through the connector hook on the Nunchuck.
Position the strap so that is coming straight through the hook, allowing you to use it after the Nunchuck has been connected.
Insert the Nunchuck connector into the expansion port on the bottom of the Wii Remote. Because the Nunchuck does not include a light or any indication of operation, you must use it in a game or Wii Channel that supports it to confirm that it is working correctly.
