There is just one screw on the front side of it that you have to use a small Allen wrench to get off. After that it should come off. Inside you will find a set of wires that runs up to the over drive button...and a sprint that operates the top push button. The first time I took mine off I had to twist and pull in one motion. It was extremely difficult to get off the first time. Just be sure the screw is out all the way and make sure to pull straight up and it should pop off. There's nothing else holding it on...it's just being stubborn.
