Ok...the pics aren't real good because I don't have a macro setting on my camera but hopefully it will give you enough of an idea that you can figure it out.
Anyway, find an old IDE cable from a computer and cut it long enough to run from your optiwiz to your buttons.
Now seperate one wire for every button you want to have. I only have one mouse button so I only pulled apart one wire. Here's the tricky part and you may be able to find some kind of diagram on the internet to help you, but you have to know which wire goes with which hole. I only used one wire, so it wasn't hard. I just tried a few differnt holes and got it on the second try.
Strip the wires you need and attach a quick disconnect the way you did with the rest of your CP. Because the wire is so thin, I striped away more than usual and doubled up the exposed wire to ensure it would be thick enough to stay in after being crimped. Attach the quick disconnect to each button.
Plug the other end of the cable onto the pins in the optiwiz. That's it.
Let me know if you have any questions.
