Hi, this may sound like a dumb question but I just bought a house but the lady whom I bought it from had security lights all around the house. She had these hooked up with a dusk til dawn sensor. I want to replace the photocell with a toggle switch, however I'm not sure what to do with the white wire. In the photocell box there is a red wire, black wire, white wire, and a ground wire (which isn't hooked up) I'm assuming the black wire is hot, the red wire is to the lights, but where do I hook the white (assuming its neutral) wire? Thanks for any help.
