I’m trying to install a GE EZ Smart (Jasco) in-wall dimmer switch to replace a dumb dimmer. This is a 3-way installation, and I can’t make heads or tails out of the existing wiring. The existing dimmer has three wires: red, black, and red with white stripes. I’m assuming the red and white striped wire is the ‘traveller’ wire and the other two are the load wires.
There are four romex cables coming into this outlet box. Three of them are two wire (black and white) and one is a three wire (black, white, and red).
The GE dimmer requires neutral, but I’m not sure how to identify which of the wires in the outlet box to connect to the neutral terminal on the dimmer. Any help would be appreciated.
Here’s a crude diagram of the existing dimmer connections and how all of the cables in the outlet are connected:
