I’m installing a new light fixture in a location that just had a cover over the box previously. I discovered that this box connected to another group of lights that is controlled by a set of 3 or 4 way switches. In the box is just one 14-3 piece of romex. I hooked up the black hots together and neutrals together and left the red Traveller alone. The light doesn’t work. I confirmed that power is going to the light. It it supposed to be wired a different way?
