3 way switches

Question

What I’m trying to figure out is 3 way switches.  I have 3 switches.  2 existing one that I would like to wire in.  On a new room.  I have 12/3 wire. And 12/2 I believe they are the travelers but not 100 % sure. They are not hot.  But when I connect the hot to them the two existing lights come on.  The picture won’t load.  So I can’t send one.

  1. First thing first. For three switches you’ll need to wire a 4 wire switch between the two 3-ways. Watch my video on 4 ways. How to install a 4 way switch
