How to Install Front and Rear Dash Cams in a Car?
3 Answers
The installation method for front and rear dash cams in a car is as follows: 1. Connect the power supply connector and start routing the wires; 2. Insert the wires from left to right into the ceiling lining; 3. Route the wires to the upper right corner and towards the door, requiring some force to pry open the side panel and insert the wires; 4. Run the wires downward along the B-pillar; 5. When reaching the door edge, pull open the door seal and insert the wires; 6. Continue routing the wires downward along the seal; 7. Remove the floor mat and run the wires underneath it; 8. Plug the dash cam into the cigarette lighter for automatic startup; 9. Turn off the device and begin routing the wires; 10. Insert the wires from left to right into the ceiling lining, and pry open the corner cover at the bend; 11. Route the wires along the gaps all the way to the rear; 12. Run the wires along the window towards the rear, pry open the seal, and insert the wires; 13. Attach the rear camera to the rear windshield and adjust the angle; 14. Align the wires and connect the rear camera power cable; 15. Finally, tuck the wires into place.
I just installed a set myself recently, sharing some experience. Installing front and rear dash cams mainly involves two parts: positioning and wiring. First, the front camera: it's best to stick it on the dotted area behind the rearview mirror on the windshield, as this won’t obstruct the view. After fixing it with an electrostatic sticker, the lens can adhere firmly—never use double-sided tape on the glass! There are two types of rear cameras: one that sticks directly inside the rear windshield, suitable for sedans; for SUVs or hatchbacks, you’ll need to drill holes near the license plate light for installation, which should be done by a professional shop. For wiring, you’ll need to remove interior panels and use a pry tool to tuck the wires along the edge of the headliner, then down the A-pillar seal to the fuse box for power. Important reminder: always use a fuse tap to connect to the ACC fuse port (Mini type recommended), and never clamp directly to the battery terminals. After connecting, use cable ties to organize the wires, or else there might be rattling noises while driving. The whole process can actually be done in about 2 hours, but pay close attention to waterproofing the wire connectors.
For installing a dash cam, I recommend preparing three essential tools: a pry bar kit, a fuse tap, and a circuit tester. Position the front camera about 5 cm behind the rearview mirror, ensuring it doesn't obstruct the driver's view. The ideal spot for the rear camera is dead center along the upper edge of the rear windshield. Routing the wires is crucial: when tucking them into the A-pillar trim from the headliner edge, avoid the airbag location (usually marked "AIRBAG" on the trim), then run them down along the door seal to beneath the floor mat. For power connection, strongly recommend tapping into the fuse box: use the circuit tester to locate an ACC fuse slot that cuts power when the engine is off, then install the corresponding fuse tap (connect the dash cam's red wire to the tap and the black wire to ground). When routing wires to the trunk, remove the C-pillar trim and leave sufficient cable slack near the tailgate hinge to prevent snapping during opening/closing. DIY installation is best done leisurely over a weekend—no rushing.
