WIRELESS INSTALLATION
1. Connect the RED wire of the wireless video transmitter to the wire that supplies power to the
reversing light (this is the wire that is energized when the vehicle is put into reverse). Please
measure the voltage on this wire to make sure that it is +12V when it is energized. Use a suitable
splicing/crimp connector (Scotch lock type) or strip back the insulation and solder the connection
making sure to insulate the connection with electrical tape or shrink tubing after the join is made.
2. Connect the BLACK wire of the transmitter to a suitable ground such as th e metal body of the
vehicle. To attach, find a suitable metal panel making sure that there are no wires and electronics
behind this panel. Drill a small 1/8th hole. Attach an “O” ring terminal the end of the BLACK wire,
then secure the wire to the chassis using a suitable self-tapping screw. To ensure a better earth
connection, scrape away the paint around the hole before screwing the terminal to the hole.
3. Plug the other connections of the transmitter cable into the corresponding sockets of the
cameras harness.
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.
Testing the reverse camera function
1.Engage the park brake and turn the ignition key to the on position. DO NOT start the vehicle.
2. Select reverse gear with the gear shift. The mirror monitor will sense the video signal from the
camera automatically and will display the camera’s image of the rear of the vehicle.
