There are 2 ways of doing it, if you have a high-definition projector, I perfer setup 2, you have not said if you are hanging your projector or if you are putting it on a table, if you are putting it on a table, just plug the cable directly from the Wii to the projector, if you are hanging it, you may want to get some RCA extention cables (long RCA cables with a male end on one end and a female end on the other) so you can feed the cables through your walls and celing to the projector.
Setup 1 (SD):
1. Feed any needed cables, if feeding your cables is not required, go to step 3
2. Give the RCA cable you fed a cable color label on both ends (yellow label for a SD composite connection)
3. Use the composite cables out of the box and plug it into your projector or your junction point (the hole in your wall where you fed your cable), if you want your sound to come out of a seprate audio system, send the white and red RCA cables to the audio system, if your audio system supports composite video output, plug the Wii into the audio system and plug the audio system into your projector, if you want your sound to come from the projector, plug the red and white wires into the projector (you will need to feed 2 more cables for the audio if you are hanging your projector, if so, label one red and the other white), make sure everything is plugged in correctly (should be color coded)
4. Turn on your equipment (Wii, audio system, if you have one that is, and your projector) and put the projector to the correct input setting, (composite), and put the audio system on the correct setting, you should see a screen telling you to press the A button, when you press it, you should hear a "click", if not, your audio system is not set up correctly, if everything works correctly, you should be ready to play
Hint: If you use this setup, you will not be able to get 420p ED/HD signals of you have an HD (High Definition) projector, if you want a better picture do setup 2
Setup 2 (ED/HD)
1. See step 1 of setup 1, if not required go to step 3
2. Same as step 2 in setup 1, the only difference is instead of labing one wire as yellow, you will be labling 3 different wires, one red, one green, and one blue, all 3 wires are for video
3. Use a Wii componet cable (not included with Wii console), use the same steps from step 3 on setup 1, but remember that you are using red, green, and blue color code labeled wires specifically for video, don't get the 2 reds confused one is for audio and the other is for video, the cables should look slightly different though, if not, the red wire closest to the white wire is probably your audio wire, just make sure to follow your color code when making all your connections
4. Turn on all your equipment, change to the correct input and settings and you should see and hear the same thing as I said before in step 4 in setup 1, if everything works correctly, you should be ready to play
Hint: for the best video quality, this is the setup you want, if your projector is not ED/HD compatible, you will need to use setup 1
I hope this is easy enough to understand, if not follow the diagram below
