INSTALLATION
The video signal is transferred from the camera to the monitor via an RCA cable that will need
to be run through the boot, through the passenger compartment to the monitors wired loom
run under the dash. From there the power and video signals are sent directly to the monitor.
At the rear of the car the camera is powered directly from the reversing tail light. Priority is the
AV2 input. We recommend that you wire up the triggers as the last part of your installation
(after the systems monitor has been wired) this is so that you can use the system as a safe
way to test for a reversing wire. Back up camera systems (reversing camera systems) require
a signal to “Trigger” the system into action so that it automatically operates when the vehicle
is in reverse. Whilst some systems are designed to allow cameras to operate even when the
vehicle is not in reverse it is still necessary to wire a trigger system in so that the Camera
that is facing backward automatically turns and or takes over as priority when in the vehicle
is in reverse. When wired in correctly using the right trigger priority, the system can also
automatically turn on the rear camera of an attached trailer taking priority over the vehicles
back up camera when the trailer is connected. The most common way to trigger the rear
facing camera is to use the + wire that powers one of the vehicles reversing globes at the
back of the vehicle.
NOTE: Some vehicles that Use CANBUS to operate rear lighting systems may require
additional parts to trigger the system. A CANBUS lter is supplied with this kit.
Caution: Never test for reversing wires standing at the back of the vehicle, with the engine
running and the gearbox in reverse gear. If the car/truck can not be placed in reverse
without the engine running, Special procedures should be employed. In this case we highly
recommend you seek a professional installer to do this type of work. Failure to follow proper
procedure could cause serious injury or death. (The vehicle could back over you).
Step 1.
Place the car in reverse, with ignition on but the car not running (do not leave the cars ignition
on for long periods of time without starting it) observe or have an observer notice which light
turns on and its location in the lens. Turn the ignition off. Then, locate the globe socket that
holds the reversing globe into the lens. In some cases the Lens has to be removed from the
car to expose the socket. In most cases however, you can gain access from the inside of the
car behind a removable interior wall/panel.
Step 2.
Identify which wire is the globes ground and which is positive (see Fig 1 picture page 3).
Light globes have very low resistance so if a globe is in place, both wires will show up as a
ground. Even if you remove the globe the second globe on the other side of the vehicle will
still give the positive side a short path to ground and may still be indistinguishable from the
globes earth. For this reason it is necessary to energize the globe to nd out which side is
positive and which side is negative. Using a multimeter set to DC volts (make sure that it is on
the correct scale) attach the negative probe to one of the globes wires and the positive probe
to the other (in most cases you can push the probe ends into the back of the globe socket) if
not, you may have to carefully strip both wires sheaths back to expose the wires core making
sure you keep them separate and away from the cars chassis to avoid any shorts).
