“How do I use my Wii Remote with the Wii U?”
1. First thing you’ll need is the sensor bar. You can use the new one that came with your Wii U or use your old one from your original Wii. (remember to remove foam pads and protective film from the sensor bar)
2. Plug the sensor end to the back of the Wii U. Place the sensor bar above the TV or under the TV. If you put the sensor below the TV you’ll need to go into ‘System Settings’ from the Home screen. Go to ‘Wii Remote and Sensor Bar’ then ‘Set Sensor Bar Position’. Set the position to ‘Below the TV’.
3. Now we need to pair the Wii Remote controller(s) to the Wii U before we can use it. Go the main menu on the Wii U, now press the ‘Sync’ button in front of the console.
4. Follow the on-screen instructions. Press ‘Sync’ on the controller to complete the syncing process.
