I completed the modification to the light switch in the back. I was so proud of it, I turned on the switch and walla, the overhead lights turned on and walla back off again no more reaching up. We got ready to sit down to watch TV Friday night, I turned off the over head lights turned on both wall sconces. Got ready to go to bed and hit the new switch to turn off the wall sconces and only the one above the new switch turned off. I guess the one on the other side is on its own 12 volt circuit. Oh well, close. I am still happy with the modification.
Next up, bathroom light switch. Hate the location under the cabinet. I already copied the notes on how to do it from your modification.
