Super simple - Plug it into the back of the Wii and then plug the HDMI cable in. Only issue is it doesn't register with my TV. Wii works fine, tested with original AV cables on an older TV and all was good. For some reason this cable just doesn't work. I tried different TVs, different HDMI ports and nothing. Then when I went to go look for product support, clicking through the buttons just sent me back to the 鶹 home page....
