Cable has Wii plug at one end; Component Video plugs & stereo audio plugs at other end.
Cable length: 170cm

COMPONENT VIDEO:
Component cables provide excellent picture quality.
Component video carries the signal in 3 wires = Y(luminance),Pr & Pb(colour information), which improves picture quality due to several technical reasons.
Component video inputs on TVs are sometimes labelled simply 'DVD', see photo for an example of Component video sockets(order of colours is not important)

Plugs into the 'AV Multi Out' socket on the back of your Wii, just like the plain AV cables that come with the machine when you buy it.
