Leviton Motion Sensor 3-Way Light Switch Installation: A Comprehensive Guide
Are you looking to add convenience and energy efficiency to your home with a Leviton motion sensor 3-way light switch? You've come to the right place. This comprehensive guide will walk you through the installation process, ensuring you understand each step and can complete the task safely and effectively.
Understanding the Components
Before you begin, familiarize yourself with the components you'll be working with. The Leviton motion sensor 3-way light switch kit includes:
- 2 motion sensor switches
- 1 standard 3-way switch
- Mounting hardware
- Wire nuts
- Screws and other necessary hardware
Safety First: Preparation
Safety should always be your top priority when working with electrical components. Before you start, turn off the power to the circuit at your home's main electrical panel. Use a non-contact voltage tester to ensure the power is off before proceeding.

Gathering Your Tools
To complete this installation, you'll need the following tools:
- Wire stripper
- Screwdriver (flathead and Phillips)
- Needle-nose pliers
- Non-contact voltage tester
- Wire cutter or scissors
Wiring the First Motion Sensor Switch
Start by installing the first motion sensor switch. This switch will be connected to the power source. Follow these steps:
- Remove the cover plate and unscrew the existing switch.
- Strip the insulation from the wires using a wire stripper. Typically, you'll see black (hot), white (neutral), and green or bare (ground) wires.
- Connect the black wire from the power source to the black wire on the motion sensor switch. Use a wire nut to secure the connection.
- Connect the white wire from the power source to the white wire on the motion sensor switch.
- Connect the ground wire from the power source to the green or bare wire on the motion sensor switch.
- Secure the connections with wire nuts.
- Tuck the wires back into the electrical box and secure the motion sensor switch in place.
Wiring the Second Motion Sensor Switch
The second motion sensor switch will be connected to the load (the light fixture). Follow these steps:

- Remove the cover plate and unscrew the existing switch.
- Connect the black wire from the light fixture to the black wire on the second motion sensor switch.
- Connect the white wire from the light fixture to the white wire on the second motion sensor switch.
- Connect the ground wire from the light fixture to the green or bare wire on the second motion sensor switch.
- Secure the connections with wire nuts.
- Tuck the wires back into the electrical box and secure the second motion sensor switch in place.
Installing the Standard 3-Way Switch
The standard 3-way switch is used to control the light from a third location. Follow these steps to install it:
- Remove the cover plate and unscrew the existing switch.
- Connect the black wire from the first motion sensor switch to the black wire on the standard 3-way switch.
- Connect the red wire from the first motion sensor switch to the red wire on the standard 3-way switch.
- Connect the white wire from the first motion sensor switch to the white wire on the standard 3-way switch.
- Secure the connections with wire nuts.
- Tuck the wires back into the electrical box and secure the standard 3-way switch in place.
Testing Your New Leviton Motion Sensor 3-Way Light Switch
Before you turn the power back on, use a non-contact voltage tester to ensure there are no live wires. Then, turn the power back on at your home's main electrical panel. Test the switches to ensure they're working correctly.
Congratulations! You've successfully installed a Leviton motion sensor 3-way light switch. This convenient and energy-efficient upgrade will provide you with years of service. Always remember to prioritize safety when working with electrical components.
