[Power Supply] → [Common Terminal (Brass] ↘[Traveler Wires (Red & Black)] ┌───────────────┐ │ Traveler │ │ (Red ↔ Black) │ └───────────────┘


[Switch A] → Common terminal

[Switch B] → Common terminal

[Light Fixture] ← Shared between Switches

Common Terminal (Brass colored): Attaches to the power source or grounded-heavy wire.
Traveler Wires (Red & Black): Connect both switches, carrying the signal.
Traveler wires run between the two switches, not the wall boxes.

Step-by-Step Wiring Guide (Watch the Process!)

Step 1: Turn Off Power

Switch off the circuit breaker controlling the light. Use a voltage tester to confirm no current is flowing.

Step 2: Install Switches

Mount the 3-way switches into separate wall boxes:

One switch at each end of the run.
Connect the common terminal to the live (hot) wire from the breaker.
Connect the traveler wires between the two switches—this is the key link.

Step 3: Run Traveler Wires

Use metal conduit or secure non-metallic cables to thread the red and black traveler wires between switches. Attach connections securely with wire nuts.

Step 4: Connect Light Fixture

Run a 14/2 cable (or existing circuit) from the light, connecting black to common on the fixture (same side as common at the switches). Ground all bare wires to metal box.
