How to Connect the Wiring for a Rearview Camera?
2 Answers
Wiring method for a rearview camera: 1. Insert the original accessory camera wiring harness into the rear license plate light hole, then snap it in directly; remove the trunk liner and pull out the waterproof wiring grommet; 2. Use a pulling wire to draw the camera wiring harness into the trunk; 3. Guide the camera wiring harness and data connector to the grommet wiring hole and reinstall the waterproof grommet, then remove the left decorative panel of the trunk and connect the integrated power and data extension cable to the camera wiring harness. The rearview camera system uses a wide-angle far-infrared camera installed at the rear of the vehicle, displaying clear images of the road behind on the in-car screen. Thanks to the far-infrared technology, visibility remains excellent even at night.
I've actually done the reversing camera wiring several times. The basic steps are to first prepare the camera and display components. The camera usually has three wires: a red power wire, a yellow video wire, and a black ground wire. You need to locate the reversing light wires at the rear of the car, typically by using a multimeter to detect the positive voltage (12V) when the reverse gear is engaged. Connect the camera's power wire there so it automatically activates only when reversing. Secure the ground wire to a body screw to ensure a stable connection. Run the video wire from the back to the front display unit and plug it in—the unit may have its own input port, so check that the connection is secure. Always disconnect the battery's positive terminal during the operation to prevent short circuits. I overlooked this initially and ended up blowing a fuse, which had to be replaced. Keep some insulating tape and wire clips handy for the job. After installation, repeatedly test the reversing action to ensure the image is clear and free from flickering. The whole process takes about an hour, but many cars now come with OEM accessory interfaces, making it much easier.
