GE 45614 3-Way Wiring?

Hi,

I am trying to install a 3-way z-wave switch but I am having trouble with the wiring. I’ve installed over a dozen single-pole z-wave switches but the 3-way is more challenging because there are so many different ways of wiring a 3-way circuit. I’ve taken a look at in both junction boxes and diagrammed the current wiring. Can someone help me understand how this 3-way is working and how I can make it work with my z-wave switch?

You need to positively identify the wires, something I cannot do from your diagram. Which is Line, Load, and Neutral? You’ll need a multimeter or voltage detector to do this. Once you’ve identified the wires, the rest will become easy.
