How to Replace a Cut Reverse Camera Cable?
3 Answers
The red wire is the positive pole with a voltage of 3.3V, the black is the negative pole, the yellow is the video line, and the white is the 12V power supply. Connect one end of the two small red-headed thin wires to the positive pole of the car light and the other end to the reverse signal detection line on the navigation system. Portable GPS devices do not need to connect this.
If the reverse camera's wiring gets cut, let me walk you through the replacement process step by step. First and foremost, disconnect the negative terminal of the car battery to ensure safety and prevent electric shock, especially since exposed wire ends can easily cause short circuits. I use a multimeter to test and pinpoint the exact break location. Once located, I carefully cut out the damaged section using appropriate tools. Next, prepare a new cable—match the gauge and color, and simply purchase a few meters from an auto electronics store. Strip the protective layer from the wire ends to expose the copper strands, then align and connect them to the camera's interface. It's best to secure the connection with electrical tape and heat-shrink tubing to ensure waterproofing and prevent leakage. After reconnecting the power, test the camera feed for clarity and functionality. If the image appears blurry or doesn’t display, double-check the soldering and connections. The entire process typically takes 30 minutes to an hour. As someone who frequently DIYs car tools and equipment, I find this approach both cost-effective and practical, preventing future breaks. Don’t forget to firmly secure the tape to keep out dust and moisture, ensuring the wiring stays intact while driving.
Replacing a broken reverse camera wire isn't complicated, let me guide you step by step. First, safety first—park the car securely and turn off the engine, then disconnect the negative terminal to prevent any electrical leakage. Locate both ends of the broken wire, usually black or red, and use pliers to trim the edges clean, removing any debris. Next, prepare a new section of wire, keeping the length appropriate to avoid tangling. Connect the new wire directly to the old ends by twisting them tightly or soldering, then wrap securely with electrical tape. Once done, reconnect the power and check if the reverse display is restored. If it still doesn't work, it might be a connection issue—just patiently redo the connection. I enjoy tinkering with these things; fixing cars yourself is both fun and cost-effective, costing around 100-200 yuan in materials while preventing future breaks due to aging. Remember to choose high-quality wires that resist heat and wear, which helps extend the camera's lifespan.
