I don't know the link off hand, I will look, but I read through it and it is easy. Just pull the sensor off the airbox and plug the airbox hole (obviously). You will need to splice some wire into the sensor wires because they will not reach. The run it to the RAM intake tube towards the front of the bike and they recommended putting it on the top or side of the tube to minimize water getting on it. Just drill a hole in the intake tube and put it in.... It sure seemed easy in the description I saw. Again, I will take a look. However, it did not sound like it helped a lot either. That's why I decided against it....
Good luck and post results!
