You really need to learn how to search , I found this link in the faq's thread very easily.

Looks like all you need to know is right there.

 

also I think you went wrong by using your dizzy.

 

Rex-Si is correct u need to use the dizzy with stamping number TD-02U the stock si/ex dizzy. ur stock one wont work.
