How to Wire a Rearview Camera?
2 Answers
The wiring method for a rearview camera involves the following 4 steps: 1. Insert the wiring harness into the drilled hole: Feed the camera wiring harness through the rear license plate light hole, remove the trunk liner, and pull out the waterproof wiring grommet; 2. Use a pull wire: Pull the camera wiring harness into the trunk; 3. Camera wiring harness and data connector: Guide the camera wiring harness and data connector through the grommet wiring hole, reinstall the waterproof grommet, and remove the left-side decorative panel of the trunk; 4. Integrated data and power extension cable: Connect the integrated data and power extension cable to the camera wiring harness. A rearview camera is a type of car camera installed at the rear of the vehicle, which, when combined with a display screen installed inside the car, forms a complete rearview imaging system, allowing the driver to see real-time video images of the area behind the vehicle while reversing.
I've installed the wiring for reverse cameras several times, and honestly, it's pretty straightforward. After removing the rear bumper or accessing the trunk, locate the reverse light. Use a multimeter to identify the positive wire, which typically shows 12V when the car is in reverse. Connect the red wire from the camera to this positive wire, and ground the black wire to a metal part of the car body. Run the video cable from the rear of the car to the driver's seat, protecting it with plastic sheathing to prevent pinching, and connect it to the display. I always keep insulating tape and connectors handy in case of exposed wires to avoid short circuits. Don’t forget to test it—check if the camera lights up when you shift into reverse and ensure the polarity isn’t reversed. As for tools, a multimeter is essential; even a cheap one will do. Safety first—never work on live wires. When routing the wires, choose hidden locations to prevent water damage during rain. Once installed, the view when reversing is much clearer, making parking more accurate.
