Where is the red wire of the reversing camera connected?
2 Answers
The red wire of the reversing camera is the video signal line, which is connected to the +12V of the reversing light. The following is a related introduction about the car reversing camera: Working principle: The reversing camera system is based on the rear-view technology of visual measurement, relying on the camera at the rear of the car to display the road conditions behind the car on the central display screen. Structural composition: The reversing camera system is divided into three parts: the camera device, the control unit, and the display. Functional role: This system makes the situation behind the car more clear and intuitive when reversing, and it is one of the very practical configurations for reversing safety.
I've installed backup cameras several times. That red wire is usually the control wire and needs to be connected to the positive wire of the reverse light. Look for it in the rear light cluster - it's typically a red or marked wire. Twist or solder it together with the red wire. When the reverse light gets power, the red wire transmits the signal to activate the camera, making it convenient and safe. Remember to disconnect the battery before installation to avoid short circuits damaging the wiring. Once my connection was loose, causing the backup camera to work intermittently, but it became stable after I secured it properly. Beginners should take it slow - no rush. Using a test pen to check for power can save a lot of trouble. Ultimately, with proper wiring, the display will automatically turn on when shifting into reverse, significantly improving driving safety.
