Where is the red wire of the reversing camera connected?

[MacGage]

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.

The red wire plays a crucial role in the reversing camera system, responsible for triggering the reverse signal, so it must be connected to the positive terminal of the reverse light. Finding the correct position is key: open the trunk and inspect the wiring harness in the taillight area, where the reverse light wire is usually distinctly colored. When connecting, use crimping pliers or soldering tools to ensure a secure connection, avoiding poor contact that could affect functionality. I recommend using a multimeter to test the circuit for proper continuity—it's simple and safe. If mistakenly connected to other wires, the camera might not activate automatically, increasing the risk during nighttime reversing. Addressing these details promptly can enhance system responsiveness and prevent future hassles of repeated repairs.

When installing, connect the red wire to the reverse light wire. Simply put: go to the rear taillight, locate the wiring connector corresponding to the reverse light (usually a red or blue wire), and connect the red wire of the camera to it. The camera will activate when the reverse gear is engaged and the light turns on. Turn off the engine during operation to prevent electric shock. Beginners need not worry; secure the connection with tape, check for looseness, and the system will run stably.
