How to Wire a Car Dash Cam?
2 Answers
The wiring steps for a car dash cam are: 1. Determine the installation position of the dash cam; 2. Simulate the wiring route first to ensure the power cord is long enough; 3. Tuck the dash cam's power cord into the gap of the car's headliner; 4. Remove the A-pillar trim panel; 5. Insert the wire into the door frame's weatherstrip, aligning it with the A-pillar clips; 6. From the top of the A-pillar, follow the door frame downward, installing the weatherstrip while tucking the power cord inside until reaching the bottom of the dashboard where the wire should emerge; 7. Pass the power cord behind the glove box; 8. Loosen the screws of the lower trim panel under the center console, tuck the wire into the gap, and then tighten the screws; 9. Plug in the cigarette lighter power supply and confirm whether the dash cam can power on and start normally.
When I installed the dash cam for my family's SUV last time, I spent a long time researching wiring methods. The key is to hide the wires without compromising aesthetics while ensuring safety. First, tuck the power cable into the windshield headliner's sealing strip, then route it down along the A-pillar. Special attention must be paid here to avoid blocking the airbag position—use a plastic pry tool to slowly tuck the wire into the interior panel gap. Next, pass it through the side of the glove box and connect it directly to the cigarette lighter. Secure the wiring with cable clips throughout to prevent loosening, leaving about 10 cm of slack for easy removal. For a more professional setup using the fuse box, you'll need to purchase a step-down cable and connect it to the ACC fuse position, then ground the wire to a chassis screw. After completion, power it on to test the recording angle, and remember to check weekly if the wiring gets pinched by the door.
