I'm trying to replace an old single pole toggle switch with a new Leviton DZ15S.
Here's the issue... The new Leviton requires 3 connections to function. Black, red, and white.
Please see the following diagram for an embarrassingly drawn "exploded" view of the plastic outlet box... (seriously, It's all I could do in paint. I tried...)
The "runs" are effectively Romex or whatever brand. Two incoming legs. The left "run 1" has 4 wires. Red, Black, White, and a bare copper. Oddly though... "run 2" only has 3 wires. I made very sure of this, but it's only black, white, and bare which is all twisted up with the bare from run 1. Nothing touches or connects to this bare ponytail.
Replace the old single pole 2 wire fan toggle switch on the right side of the diagram. The new Leviton smart switch will require a "black", a "red", and a "neutral" connection to work. This is the problem, I'm not sure where to get these from and I don't want to guess... because it seems like a real bad idea to guess with things like this.
Tools I have: Basically everything for standard electrical work. Pliers, half jaws, stripper, electrical tape, Fluke volt/ohm meter, twist caps for binding wires, etc. I'm sure I have whatever I need - just not sure what to do here...
Please help! and Thanks!!
