Turns out I have 5 wires coming into the 3 way switch/box. There are 3 black wires, 1 red wire and 1 ground wire.
I've identified one of the black wires as the common/hot, using a multimeter. My question is, do I combo the other 2 black wires together, or should 1 of the other black wires combo with the common?
Why would they run 4 wires (plus the ground) instead of 3?
