Electronic – Connecting the Wii remote to a computer via Bluetooth

Without knowing which BT module you are using it will be a little difficult to help, but. As mentioned above using the BlueSMiRF board and some jumper wires you can attach

• 5v to PWR
• (-) to GND
• tx to RX - I
• rx to TX - O

If you have a specific BT module you are working with update your question and we can try to be more helpful.

Unfortunately it's not a good idea to do that with a $40 Wii remote, designed to track the position of IR emitters, not data signals. You could do it with a < $10. part such as http://www.sparkfun.com/commerce/product_info.php?products_id=8554 . See also http://www.gumbolabs.org/2010/05/29/radioshack-infrared-receiver-arduino/
