Upgrading your home lighting system can seem overwhelming, especially if you’re trying to create a 3-way setup (2 switches controlling the same circuit). Fortunately, with RunLessWire’s 3-way switch kit, this task becomes incredibly easy and hassle-free. Let’s explore how straightforward the installation process is and why it’s a smart choice for any homeowner.

Step-by-Step Installation Guide

1. Gather Your Tools and Kit Components

Before starting, ensure you have the RunLessWire 3-way switch kit, a screwdriver, and possibly a voltage tester for safety.

2. Turn Off Power

Safety first! Turn off the power to the existing light switch at your circuit breaker. Use a voltage tester to confirm that the power is off.

3. Remove the Existing Switch OR Open up Fixture

You can choose to install the receiver either at the switch location or the fixture location. The receiver requires a neutral wire, so if it is not available at the switch location, it should be at the fixture location.

If installing at the fixture location, just remove the screws from the fixture to expose the wires.

If installing at the switch location, remove the faceplate and the screws holding the existing switch in place. Carefully pull the switch out of the electrical box, making sure not to touch any wires.

4. Install the Receiver

The receiver is the heart of the RunLessWire system. Connect the receiver to the existing switch wiring. The receiver has clear labels indicating where each wire should be connected:

  • Connect the hot wire (usually black) to the BLACK wire on the receiver.
  • Connect the load wire (also black) to the BLUE wire on the receiver.
  • Connect the neutral wire (white) to the WHITE wire on the receiver.
  • If there’s a ground wire (green or bare), just cover it with a wire nut.



5. Secure the Receiver

Carefully tuck the wires and the receiver into the electrical box. Replace the fixture, or if installed at the switch location, either cover with a blank faceplate or install one of the wireless switches there. 

6. Install the Wireless Switches

The wireless switches come with adhesive backing for mounting on a flat surface, or screw mounts to mount at the original switch location without the backplate.


7. Test Your Setup

Turn the power back on at the circuit breaker. Test the wireless switches to ensure they control the light as expected.
