WIRED INSTALLATION
1. Connect the RED wire of the Cameras Power Harness to the wire that supplies power to the
reversing light globe (the wire that is energized only when the car is put into reverse). Before making
the electrical connection, temporarily disconnect the camera from the power plug whilst making the
connection to the reversing light globe. Use a suitable splicing/crimp connector (scotch lock type) or
strip connector. This connection can also be soldered, making sure to insulate the joint with electrical
insulation when done. The camera has only one wire to connect (positive (+). There is no need to
hook up a ground earth wire as the camera gets its earth through the RCA cable. Hooking up the
ground earth may cause a ground loop. In this case horizontal lines will appear in the image.
2. After you have insulated the join you can connect the power harness to the camera.
NOTE:
Some cars that run LED or computer controlled lighting systems may not deliver enough
voltage to run the camera. If the voltage at the reversing wire light is less than +12 volts it may be
necessary to use a relay to supply power to the transmitter harness from the wiring in the front of
the car. In this case the reversing light only needs to trigger the relay. Make sure that you do not
drill holes in the panels that have an opposite face that is visible outside the car for example guard
panels. In fact, whenever drilling holes in the bodywork of a vehicle, always see what is on the other
side.
3. Connect one end of the supplied RCA cable to the RCA socket from the camera, then run the
RCA cable to the front under side of the driver side dash board. This is where the mirror monitor’s
loom will be located. To do this you will need to remove the rear seat to pass the cable into the cabin
area and you will need to remove the door scuff plates to run the wire along the side of the vehicle.
The RCA cable will be hidden when you replace the scuff plates. When the cable is at the front of the
vehicle the RCA cable needs to be run from the scuff plate area to the underside of the dash behind
the kick trim (remove and run cable).
4. The mirror mount monitor has two power wires to be connected. Connect the red wire
(acces12V) to a wire that is energized when the vehicles accessories is turned on.
Connect the black wire to a ground earth wire or to the body of the car using the steel of the cars
body behind the kick trim as an earth. In this case drill a small hole and connect the wire using a
suitable ring terminal. Scrape off the cars paint around the hole to ensure good earth.
5. Connect the RCA cable to the RCA socket from the monitors loom.
