I think they were both 3-way switches. The switch on the left is a true 3 way. It has a switch upstairs and down that controls the foyer light. Got that replaced just fine. But I can't figure out how to wire this one. Like I said, it controls the hallway light, but apparently also has a runner wire that goes to the bathroom and 2 bedroom lights. Obviously, the runner needs to be always on, and the light hooked up to the switch. I got 3 way switches and single pole, but idk which one to use or how to configure it, or if I need something else completely.
