It's quite easy. Two screws under the housing, and a small button under the clutch safety switch. Push the button with a small screwdriver while gently pulling on the switch.
Now unplug the housing from the harness and you have to jump the safety switch. With a small solid wire strip the ends and plug it into the black wire and the black/orange wire. Tape the whole thing up very well so the wire will not fall out. Test the bike starts, and you are done.
If it won't start make sure the kick stand is up, and your connection is solid, and try again. Now you will always have to make sure the clutch is pulled in, or she will run off on you during your start.
