From the original instructions on yosief's site:
"Connect the Mode Up wire by putting a Molex connecter in Slot 22 (2001-) or Slot 21 (1997-2000). Connect the Reset wire by putting a Molex connecter in Slot 24 (2001-) or Slot 25 (1997-
2000)."
These are the two I used, and one side of the rocker scrolls through the different options, and the other side acts as the "reset" when held down.
