Things You'll Need
Instructions
Connect the rectangular end of the Wii's component cable to the "Digital AV Out" slot, found on the back of the Wii console itself.
Connect the colored plugs on the other end of the component cable (the three video plugs are colored red, green and blue, while the two audio plugs are colored red and white) and insert them into the corresponding colored jacks on the HD converter box (for example, insert the green plug into the green jack on the converter box).
Connect one end of your HDMI cable to the HDMI slot on the converter box (it should be labeled "HDMI"), then connect the other end of the HDMI cable to the HDMI slot on the television. (Again, it should be labeled "HDMI," though the exact placement of this slot depends on your model of television.)
