3. Installation
3.1 Wiring Diagram (Fuse Box Connection)
This system is typically powered via the vehicle's fuse box. Follow the diagram below for standard installation.
- Connect the red wire of the power cord to an ACC (Accessory) power source (9-36V) in your fuse box. This ensures the system turns on/off with the vehicle ignition.
- Connect the black wire to a metal ground point (GND) or an iron part of the vehicle chassis.
- Connect the green wire to the reverse gear circuit. This acts as a trigger, automatically displaying the reverse image and guidelines when the vehicle is in reverse (if the camera is connected to CH2).
- Connect the camera to the CH2 input of the monitor using the 66ft extension video cord.
- If continuous observation is desired (e.g., while driving or parking), connect the camera to CH1 and disregard the green reverse wire connection.

3.2 Alternative Power Connection (Car Charger)
For a simpler installation without connecting to the fuse box, you can use the provided car charger (spare) and DC Terminal Conversion Cable.
- Connect the DC Terminal Conversion Cable to the power input of the monitor.
- Plug the car charger into your vehicle's cigarette lighter socket.
- Connect the DC Terminal Conversion Cable to the car charger.
- Note: If using this method for continuous observation, the system will only be powered by the car charger. If you require the reverse trigger function, it is still necessary to connect the green reverse cable to the fuse box as described in Section 3.1.

3.3 Mounting the Monitor and Camera
- The 7-inch LCD monitor can be attached to the dashboard or windshield using the provided brackets. Ensure the mounting location does not obstruct your view or interfere with vehicle controls.
- Mount the camera securely at the rear of your vehicle, ensuring a clear line of sight. The IP69K rating ensures durability in various weather conditions.
4. Operating Instructions
Once installed and powered, the system will automatically activate when the vehicle is turned on (if connected to ACC).
- Power On/Off: The monitor will automatically turn on/off with the vehicle's ignition if wired to ACC.
- Channel Selection: The monitor supports two video inputs (CH1 and CH2). Use the buttons on the monitor to switch between channels. CH2 is typically used for the backup camera and can be triggered by the reverse gear. CH1 can be used for an additional camera (e.g., front or side view).
- Menu Settings: Access the OSD (On-Screen Display) menu using the monitor buttons to adjust settings such as brightness, contrast, color, and display mode.
- Reverse Trigger: When the green wire is connected to the reverse circuit and the vehicle is put into reverse, the monitor will automatically switch to the CH2 camera view and display parking guidelines.
