2010-03-27 04:43:18rev. 3ERROR FIXEDThere is a picture missing to show pin numbering. Pin 2 is not "No Connection" but is used by the remote to detect presence of the Nunchuk (pin 2 and 3 shorted in Nunchuk to give 3.3V back to remote when Nunchuk is connected).APPROVED

2024-06-26 23:51:26rev. 8INCORRECTTwo issues: shown plug/socket is not for Wii Nunchuck but FireWire. And pin numbering and description also do not match. Description for pin 3 suggests pin 2 should be 3.3 V but description of pin 1 says GND. The numbering itself also looks suspicious since it does not match any usual pin numbering schemes (along/across/clockwise/counterclockwise) but lacking a proper plug/socket picture this is just a guess. https://wiibrew.org/wiki/Wiimote/Extension_Controllers has a picture of the plug with correct signal mapping.WAITING FOR APPROVAL
