What is the installation method for the rear camera of a Civic dash cam?

[DiKingston]

Installation method for the rear camera of a Civic dash cam: 1. Plug in the rear camera connector and the power supply on the cigarette lighter, then check if both front and rear cameras are functioning properly; 2. After confirming everything is correct, start routing the wires; 3. Insert the wires into the plastic panel above and connect to the fuse box; 4. Use a trim tool to guide the rear camera wire to the rear windshield and remove the panel above the rear glass; 5. Pull the wire through the hole and install the camera in the position of the removed panel. Taking the 2020 Civic as an example, its body dimensions are 4517mm in length, 1799mm in width, 1434mm in height, with a wheelbase of 2700mm.

I just installed a rearview camera on my Civic by myself, and the steps weren’t too complicated. First, determine the camera position—the best spot is the upper part of the rear windshield’s interior. Routing the wiring is the most critical part: use a plastic pry tool to tuck the wire into the headliner gap, run it down along the A-pillar trim, and pass it through the door seal to the trunk. Be careful when removing the trunk trim to route the wire—avoid pulling too hard. After securing the camera, connect the head unit’s end by running it along the trunk’s side and under the rear seats, then finally connect the power to the cigarette lighter or fuse box. Throughout the process, ensure the wiring doesn’t block the airbag positions, as that could compromise safety. If the wiring gets stuck during routing, spray some dashboard wax for lubrication. After installation, adjust the camera angle to ensure a clear view of three rear lanes.

Safety and aesthetics are the top priorities during installation. First, turn off the vehicle's power to avoid short circuits and blown fuses. Secure the wiring neatly using zip ties, hiding it within the headliner and rubber seals for a clean look. When routing wires in the Civic's trunk, remove a few clips using a plastic pry tool—never use a screwdriver to avoid scratching the interior. Attach the camera to the inside of the rear window after cleaning the glass with 3M adhesive. For power, connect it to the ACC terminal in the fuse box to enable parking surveillance. During final adjustments, ensure the camera avoids the rear wiper's range to prevent obstruction. Keep the anti-glare film handy after installation, as nighttime reflections may affect performance.

Basic installation in three steps: positioning, routing, and wiring. The camera is attached slightly above the center point of the rear window after removing the protective film. Route the wires by tucking them along the edge of the car's headliner, and when passing the B-pillar, lift the door seal to hide the wires. For the trunk section, remove the right-side decorative panel to expose the wiring channel. Plug the camera's connecting cable into the corresponding port on the main unit, and connect the red power wire to the cigarette lighter extension cord. Secure any loose wiring with tape throughout the process to avoid rattling noises. Power on and adjust to ensure the image is free from glare and the angle covers the rear view directly.

When installing, I pay the most attention to hiding the wires. The Civic's headliner and windshield have a flexible gap where you can tuck the wires without tools. Pry open the A-pillar trim and press the wires inside for a concealed route. The door seal can be pulled open to hide the wires. The tricky part in the trunk is the transition to the interior; the Civic has a round rubber grommet—pierce it and guide the wire through. When attaching the camera to the glass, place a cloth underneath and press firmly for five minutes. Power connection varies by preference: the cigarette lighter is the easiest, while the fuse box looks cleaner but requires a fuse tap. After installation, wipe the lens clean with a soft cloth and adjust to a 15-degree downward angle for optimal positioning.

Advanced installation requires attention to detail. Prepare plastic pry tools, insulating tape, and a voltage tester. Route wiring away from airbag locations; areas with airbag labels on Civic A-pillars must not be disturbed. Using a wire for trunk cable routing is most effortless. Ensure the waterproof rubber ring on the camera's host connector is intact when connecting. For power supply, it's recommended to connect to the constant power terminal in the fuse box, and remember to add a 5A fuse for protection. During debugging, use a smartphone to view live footage, adjusting the angle to see the lower edge of the rear bumper. If clips break during installation, purchasing identical replacements online costs just a few cents. Leave 10% extra length in cables to prevent breakage from door opening and closing.
