This is way overkill for getting to the light switch. All you do is remove the side panel, it just pulls off. Then pull the top of the lower kick panel, it will just fold down, then remove the two screws like in the pics, then just pull it towards you. The top will come out a little but thats okay, just make sure to puts the slots back in straight when going back together. I believe the wire you want is the one next to the far left, it should be orange with a black stripe. Just put a t-tqap on it and you'll be all set-up.
