The wiring steps for the reverse camera are: 1. Disconnect the battery power supply connection; 2. Remove the small license plate light and pass the wiring harness through the position of the small license plate light; 3. Connect the adapter cable, with red connecting to the positive pole and black connecting to the negative pole, and connect the signal wire of the camera to one end of the signal extension cable; 4. Connect the signal extension cable to the display; 5. After completing the wiring, restore the battery power supply. The reverse camera, also known as the parking assist system, is a safety auxiliary device for parking or reversing a car. It can display images to inform the driver of the surrounding obstacles, eliminating the trouble caused by the driver looking around when parking, reversing, or starting the vehicle. It helps the driver eliminate blind spots and unclear vision defects, improving driving safety.
The wiring process for a reversing camera mainly involves four steps: First, start by removing the interior trim panel from the trunk to locate the wiring harness of the reverse light. Use a test pen to identify the positive wire of the reverse light (usually red or yellow), then connect the camera's power wire to it, ensuring to cover it with heat shrink tubing or wrap it tightly with insulating tape. Next, route the video cable along the rubber door seal, leading it all the way to the dashboard. The third step involves removing the center console panel to locate the AV input port on the back of the head unit and firmly plugging in the video connector. Finally, connect the camera's black wire to a nearby metal screw on the car body for grounding. Use zip ties to secure the wiring to prevent rattling noises. Before reassembling the trim panels, test the image clarity by shifting into reverse gear to ensure everything works properly. If you're unsure about the process, it's more convenient to take the car to an auto repair shop.
Having worked in auto repair for years, I've installed hundreds of backup cameras. The core wiring involves three key connections: connect the camera's power to the reverse light's positive terminal, being careful not to damage the original wiring when stripping the insulation; route the video cable through the license plate light area into the trunk, then along the inner side of the roof trim to the dashboard; finally, ensure the ground wire has a solid connection. The crucial point is to conceal the wiring—door seal rubber strips can perfectly hide the cables. At the dashboard end, identify the vehicle-specific interface—older cars use RCA connectors, while newer models often have dedicated pin connectors. Always disconnect the battery's negative terminal before power testing to prevent short circuits and blown fuses. After installation, adjust the camera angle to ensure coverage within three meters behind the vehicle. Beginners are advised to wear insulated gloves throughout the process.
