I am swapping the light switches in my house and have come across some issues with some of the 3-way switches. The switches have a ground, two red cables, and two black cables and the new switch I'm putting in has ground, one traveler cable, and a neutral that I need to twist into the box myself.
In order to make this compatible, I believe I would need to twist together the two black cables (as I have been doing for the other add-on boxes) but that still leaves me with two red traveler cables for one hole on the back of the dimmer as pictured below.
I have been using their normal steps listed in their documentation (https://byjasco.com/media/manuals/46199-QSG-v1.pdf) but want to make sure I get it correct.
Is the best method to combine the traveler wires in a cap and lead a third one out? Is it safe to connect both red travelers in the two openings at one connector (Pretty sure I've read that this is not the way to go)? Is the solution something completely different?
