I'm just a novice when it comes to electrical stuff so please bear with me. There are just three wires that were connected to the old switch: black, white, and green. What do I have to differently to the keypadlinc? It doesn't appear to be getting any power because I hold the buttons down for more than ten seconds and nothing happens. What sucks is I have no way of knowing if it isn't getting power or if it's just a dud. It would seen to be as simple as hooking up the wires, but obviously that is not the case. What exactly do I have to do to 'rewire the juntion box' to give the keypadlinc power all the time?
