I am trying to connect the Leviton VPT24-1PZ Vizia 24-Hour Programmable Indoor Timer with Astronomical Clock in a 3-way setup w/ LED lights. There was previously another light timer there (prob ~30 years old and couldn't properly keep time). On the other end of the circuit is a light switch.
I am attaching two photos:
Wiring going into the existing light switch on the one end. To be honest, I don't care about keeping it if it made the installation of the Leviton timer easier.
Wiring from the old light timer, which I am now replacing. I note that it only had the 3 wires coming out of it and wasn't connected to the copper/ground. The Leviton timer has 5 wires coming out of it.
