How to Install a Rearview Camera?
3 Answers
First, disconnect the power supply cable from the battery and keep the disconnected cable away from the electrodes to prevent accidental power connection. Prepare the rearview camera wiring harness, remove the license plate light, and pass the wiring harness through the position of the license plate light. Use the clips inside the removed license plate light to install the camera, then screw the removed bulb onto the camera. Route the extension wire to the dashboard through the trunk power line and the car's threshold panel; connect the signal extension wire to the display.
Last time I installed a rearview camera on my car, the whole process went pretty smoothly. First, take some time to prepare the tools and kit—buy a set that includes the camera, display, and all necessary wiring, matching your car model. The camera is usually fixed above the rear license plate, secured with screws or strong adhesive, and adjusted to face the rearview properly. Then, route the wiring: connect the power cable to the reverse light circuit, which typically activates when shifting into reverse gear. Use a multimeter to check the voltage and ensure correct wiring—don’t mix up the positive and negative. Mount the display on the dashboard or suction it to the windshield for easy viewing while driving. Hide the wiring along the car’s weather stripping or under the carpet to avoid loose cables. Finally, test the system by shifting into reverse to ensure the image is clear and lag-free. The whole process requires a screwdriver and electrical tape and took about two hours, but saved me a few hundred bucks in repair costs. The key is patience—the first installation might be slow, but following online video tutorials will get it done. Just remember to protect the wiring from being crushed.
Key points to note when installing a reverse camera: Choose the camera position carefully, typically at the central height of the rear bumper to ensure a wide field of view. Secure the wiring properly, connecting the power to the positive terminal of the reverse light, and use a multimeter to check for short circuits or interference. Install the display in a comfortable position for the driver, such as a rearview mirror-style or center console screen. When routing the wires, pass them through sealed areas of the body and use protective sleeves to prevent friction and disconnection. During testing, engage reverse gear to check the response speed and image quality—excessive delay may indicate poor wiring. It's advisable to choose waterproof and shockproof equipment for better durability. While DIY installation can save money, if you're unfamiliar with circuits, it's safer to have a professional handle it, especially for vehicles with screens that may require a decoder. After installation, regularly inspect the wiring and connectors for any issues.
