How to Route the Dash Cam Wiring?
3 Answers
Method for routing dash cam wiring: First, secure the dash cam in place. Then, tuck the dash cam wire along the intersection of the roof lining and the windshield. Continue routing the wire along the edge to the A-pillar, then through the door seal and under the glove compartment. Finally, insert the wire along this path into the gaps and plug it into the car's cigarette lighter. Before installation, the first thing to do is measure whether the dash cam's wire is long enough. If the wire is too long, it can complicate the routing process. The second step is to position the dash cam correctly. Some drivers install it in the wrong location, partially blocking the rearview mirror, which hinders their view of the interior. Next, check if the dash cam comes with a memory card. If not, you'll need to purchase one separately. Without a memory card, there's no storage space for recorded footage. During installation, there are specific steps and precautions to follow.
When installing my dash cam, I put effort into cable management to avoid a messy look. After positioning it at the center of the windshield, I routed the wire along the edge gap of the roof lining, gently tucking it in with a plastic pry tool until reaching the A-pillar. There, I concealed the wire beneath the rubber seal or interior trim to keep it hidden. Then, I connected it downward to the cigarette lighter power source—though tapping into an unused fuse slot would be more stable, preventing voltage fluctuations. I made sure to turn off the engine during installation to avoid short-circuit risks. The entire cable was secured with double-sided tape or zip ties every 20 cm or so to prevent shaking while driving. Once done, the interior looked clean and tidy, with stable recording performance—I found the DIY process quite satisfying. Next time, I might try adding a rear camera, following a similar routing path but with an extra layer of cable concealment. Remember to plan the routing diagram first to minimize rework.
When driving my kids to and from school, I pay special attention to the safety details of dashcam wiring. Wires must not be left loose, otherwise kids might touch them or they could block the view, causing trouble. My method is to route the wires along the inner side of the roof and A-pillar, tucking them into the gaps to ensure they don't interfere with steering or gear shifting. Powering it through the cigarette lighter is simple, but for safety, I recommend using a dedicated fuse box interface for better reliability. After installation, check that the wires are secure and inspect their condition weekly to prevent aging from affecting performance. With the wiring properly set up, the recording is clear and free from interference, making driving more reassuring. As a parent, I believe this small step helps avoid potential hazards and is worth promoting. Family car owners should learn more such techniques—safety first should never be overlooked.
