Wiring Liftmaster 850lm Conversion Kit

I recently ordered the Liftmaster 850LM conversion kit for my Sears model 139.655300 opener. I needed the conversion kit because I dont have any remotes for the opener. Well, when I received the kit, it does not provide directions on how to connect the conversion so I can use the openers. Can you please help with the installation?
