I want to wire a Leviton programmable timer to my outdoor lights. The Leviton has a black, red, white, orange (for 3 way) and green wire. The box has one black, one white and one ground wire. I am ignoring the orange wire since there is only one switch controling the lights. I have wired the timer green to the ground and the whites together. What to do with the black and red from the timer and the black at the box?
It will not work, if there is a "Switch Leg". You need a Neutral, which would mean having four wires, not just three, so that you can use the timer. If you can pull 14/3, that would allow you to use the timer.
