2 Answers
Here are the steps for installing a rear camera for a dash cam: 1. The first step is to disassemble the relevant components. Mainly the following areas: (1) Remove the rubber sealing strip of the passenger-side door. (2) When removing the A-pillar interior trim, if the vehicle has round fixed covers, use a screwdriver or flathead screwdriver to open the cover and then unscrew the internal screws. (3) Use both hands to pull and remove the passenger-side A-pillar interior trim. (4) Use a screwdriver or flathead screwdriver to remove the B-pillar interior trim, leaving a small gap between the headliner and the B-pillar trim. 2. The second step is to connect the rear wiring. (1) Connect the front and rear wiring to the front lens CAM-IN. (2) Use your hands to tuck the wiring into the gap between the windshield and the headliner. (3) Conceal the wiring inside the upper part of the A-pillar interior trim. (4) Tuck the wiring into the gap between the passenger-side body and the headliner. (5) Insert the wiring into the gap between the B-pillar interior trim and the headliner. (6) Connect the wiring to the rear camera. Organize the remaining wires to complete the installation. (7) After installing the rear camera at the top center of the rear glass, tuck the rear wiring all the way into the C-pillar interior trim, between the headliner and the rear glass. (8) Insert the rear wiring into the gap between the C-pillar interior trim and the headliner. (9) Use insulating tape to organize the remaining rear wiring. (10) Tuck the organized rear wiring into the gap between the rear seat body and the headliner. Organize the remaining wires to complete the installation.
I recently installed a rear camera for my dash cam by myself, and the whole DIY process was quite simple. First, make sure the dash cam itself supports an external camera; otherwise, you’ll need to upgrade the device. I bought a compatible wide-angle camera on JD.com for a little over 100 yuan. The installation position was glued to the center of the rear windshield, ensuring it didn’t block the rearview mirror’s line of sight. The wiring was the most challenging part: I used plastic clips to route the cable along the door seals from under the dashboard to the rear of the car, hiding it in the seat seams without damaging the interior. For connection, just plug it into the dash cam’s dedicated port or AV input. After testing, the footage was super clear, covering the full rear view, which gave me extra peace of mind, especially when driving in the rain. I recommend buying a camera with night vision for use in low-light conditions. When routing the cable, avoid sharp bends to prevent breakage. The whole process took less than two hours—great value for money and a significant safety upgrade.
