I have a 4 way circuit as shown in the the picture below. Power comes in to the light's box and goes to the switch from there.
Can I use the DW6HD and two of the DD00R in this configuration? Below is the wiring diagram from Leviton, it just doesn't show how to wire the switches when the Line wire starts at the light and is also the Load (not sure if saying that proper):
I believe with the wires I have now it won't work and I need to have a new 14-3 wire installed from the light to the switch labeled Top Stairs? After that it should work?
