How to Connect the Wiring for a Rearview Camera?
3 Answers
Methods for connecting rearview camera wiring: 1. Insert the original accessory camera wiring harness into the drilled hole of the rear license plate light, then snap it directly into place; 2. Remove the trunk liner and pull out the waterproof wiring grommet; 3. Use a pulling wire to draw the camera wiring harness into the trunk, guide the camera wiring harness and data connector to the grommet wiring hole, then reinstall the waterproof grommet; 4. Remove the left-side decorative panel in the trunk and connect the integrated data-power extension cable to the camera wiring harness; 5. Follow the original vehicle wiring harness to route it out from the rear trim panel, peel back the sealing strip near the left door edge of the rear seat, guide the wiring into the rear cabin, pull out the integrated data-power plug and remaining extension cable, then restore the trunk; 6. Tuck the extension cable into the plastic panel gap along the door edge all the way to the cockpit door edge; 7. Remove the storage compartment below the headlight, pass it above the OBD interface, then connect the wiring port to the navigation device's interface.
Connecting a reverse camera circuit isn't overly complicated. Step 1: Prepare basic tools like wrenches, Phillips screwdrivers, and electrical tape. The camera is typically mounted near the rear license plate area. Step 2: The key task is routing the camera's video output cable from the rear bumper to the dashboard inside the vehicle. Run the wiring along the underside of body panels or door edges to avoid crushing damage. Step 3: Connect the activation signal wire (usually a thin red wire) to the reverse light circuit. Open the trunk lid, locate the reverse light power wire (typically the positive pole), use wire strippers to expose a small section, then twist and secure the connection. Step 4: Provide power to the camera. If the system requires additional power, connect it to ACC power or the cigarette lighter socket. Finally, ensure all connections are tight and properly insulated, checking for exposed wires that could cause short circuits. During testing, shift into reverse gear to verify the display shows clear, interference-free images. Exercise caution throughout to prevent electric shocks or blown fuses. If unfamiliar with the process, seeking professional assistance is advisable. Remember to keep wiring tidy to prolong service life.
As an average car owner, I follow simple steps when connecting a reversing camera. First, purchase a good kit with installation instructions. Mount the camera at the rear of the vehicle, then carefully thread the wiring into the car interior, routing it along the trunk and under the seats to keep it as hidden as possible. The key step is connecting the signal wire to the reverse light: locate the reverse light wiring harness in the trunk (usually the red wire is positive), use wire cutters to join the red and black wires, and secure them with electrical tape to prevent loosening. The camera's power cable can be connected directly to the cigarette lighter or wired into the vehicle's electrical system using the included transformer. Plug the video input cable into the display, typically positioned near the dashboard. After installation, test the image by shifting into reverse. If the image appears blurry or the screen goes black, it might be due to loose connections or corroded contact points—simple cleaning should resolve this. The entire process takes about an hour, requires basic tools, and is manageable for beginners. If unsure, having a repair shop handle the installation ensures safety and peace of mind when reversing.
