Found these in my draw from when the Wii originaly came out
they use quick solder boards so u just place them over the designated points and put a bit of solder on them.
I originally bought these for my wii but got a wiikey instead
theres 5 here so not looking for a lot as i assume u can only use these on the original v1 wii. so £10 will secure inc postage
