Installed it on mine and did just as dmod said to do. When finished you will notice there is about a 3/4 inch gap between the dmd and back box panel. At the right angles you will be able to see inside the back box and wires which really annoyed me. Just doesn't look right. So I bought black weather stripping and went all the way around and sealed it. Came out perfect and you can't tell that there's a gap anymore. Really suggest doing this unless you don't care about seeing that stuff
