3.2 Wiring Connections
The monitor operates on a DC12V-24V power supply. Connect the power cable to a suitable power source in your vehicle. Ensure correct polarity (Red to positive, Black to negative/ground).
3.2.1 Rear View Camera Wiring (Common for 4-PIN and AV)
This diagram illustrates connecting a rear view camera to the monitor, typically triggering when the vehicle is in reverse.

Figure 6: Rear View Camera Wiring Diagram
- Power Connection (Monitor):
- Red: DC 12V+
- Black: GND (Ground)
- Camera Connection (Rear View):
- Connect the camera's video output to the monitor's video input (V1 or V2).
- Connect the camera's power (Red: 12V+) to the vehicle's reverse lights (12V+).
- Connect the camera's ground (Black: 12V-) to the vehicle's ground.
- Connect the monitor's BACK/Reverse (Display trigger line) to the vehicle's reverse lights (12V+). This triggers the monitor to switch to the rear camera view when reversing.
3.2.2 Front View Camera Wiring (4-PIN Example)
This diagram shows how to connect a front view camera, which may be continuously on or triggered by another event.

Figure 7: Front View Camera Wiring Diagram
- Camera Connection (Front View):
- Connect the camera's video output to the monitor's video input (V1 or V2).
- Connect the camera's power (Red: 12V+) to a switched 12V+ source in the vehicle.
- Connect the camera's ground (Black: 12V-) to the vehicle's ground.
- Connect the monitor's BACK/Reverse (Display trigger line) to a suitable trigger if automatic switching is desired, or leave unconnected for manual switching.
