To wire a 3 way light switch you ll need 2 3 way light switches 2 2 wire non metallic cables 1 3 wire non metallic cable and 2 6 inch grounding wires.

So what you should see if you have correct 3 wire electrical cable romex is a black power white neutral and now a 3rd red wire. In this diagram the electrical source is at the first switch and the light is located at the end of the circuit. As it is three way switching wiring connection we have used two switches one is ordinary 3 way switch and the second one is 3 way pilot light switch. Wiring diagram 3 way switch with light at the end.

With a pair of 3 way switches either can make or break the connection that completes the circuit to the light. Wiring a 3 way light switch is certainly more complicated than that of the more common single pole switch but you can figure it out if you follow our 3 way switch wiring diagram. First run a 2 wire cable from the wall power to the black screw on 1 of the switches.
