4. Setup and Installation
This extension cable is specifically designed for use with rear-view mirror driving recorders that support "front and rear dual recording + reversing mode" and are originally matched with a rear pull-back camera. It is not suitable for re-equipped or aftermarket cameras that were not originally part of the system.
- Identify Connector Type: Ensure your existing rear camera and DVR/monitor have compatible 4-pin or 5-pin 2.5mm connectors.
- Connect Camera: Plug the 2.5mm jack end of the extension cable into your rear-view camera.
- Connect DVR/Monitor: Plug the other end of the extension cable into the corresponding input port on your DVR or rear-view mirror monitor.
- Connect Reversing Light Wires: The extension cable includes red and black wires.
- Connect the red wire to the positive (+) terminal of your vehicle's reversing light circuit.
- Connect the black wire to the negative (-) terminal or a suitable ground point.
Important: Incorrect wiring of the reversing light wires may prevent the reversing image function from working correctly or cause damage. If unsure, consult a professional auto electrician.
- Route Cable: Carefully route the extension cable through your vehicle's interior, ensuring it does not interfere with moving parts, airbags, or obstruct your view. Secure the cable using clips or ties to prevent it from snagging or becoming loose.
- Test System: After installation, start your vehicle and engage reverse gear to test if the reversing image is displayed correctly on your DVR/monitor.

- Ensure your DVR/monitor settings are configured to recognize and display the rear camera input. Refer to your DVR/monitor's user manual for specific settings.
