What is the red wire and what wire does it go with when there are three wires black red and white?
Red, white, and black are standard for a three-way switch (you have two switches that control the same fixture). You should also have a ground wire (copper, unsheathed). The black and red are negative, while the white is positive. It works pretty simply. When the switch is up, the black and white are linked, creating a circuit. When it is down, the red and white are linked. If both switches agree (both are red/white or both are black/white), then the circuit is completed and power flows.
