Go to the market place on your iPod Touch and search for "Wiimote." There are many applications to choose from, including "Wiimote Controller," "Wii ControllerIME" and "snes4iPhone." Read the description for the software to determine if it provides the features you desire. Select a free version of the Wiimote software, or pay a small price for additional features. Download and install the selected program.
Locate the Wiimote application on your iPod and touch it to open the application. You will see a black screen, followed by a screen indicating that the program is attempting to track devices.
Hold the "1" and "2" buttons on your Wii remote simultaneously until the blue lights at the bottom begin to flash.
Watch the screen on the iPod for a picture of a Wii remote, which indicates that the devices have been synced. Move the Wii remote around while watching the iPod screen. The screen will display a Wii remote moving in sync to your movements.
