4. Once the motion detector is securely mounted, inspect the wiring connections on the back of the device. Some motion detectors may have pre-wired leads, while others may require you to connect the wires manually.
5. If the motion detector has pre-wired leads, simply match the corresponding wires to their respective colors. For example, connect the black wire to the black wire, the white wire to the white wire, and so on.
6. If the motion detector requires manual wire connections, use wire strippers to remove a small section of insulation from the ends of the wires. Then, use wire connectors to join the corresponding wires together. Typically, the black wire connects to the black wire, the white wire connects to the white wire, and the green or copper wire connects to the grounding wire.
7. Ensure that all wire connections are secure and tightly fastened. Use electrical tape to wrap around the wire connectors for added protection and to prevent any accidental disconnections.

Once you have installed the motion detector, you are now ready to proceed to the next step: connecting the motion detector to the porch light.
