1. Remove the rear iiccosc pUlc to determine ihe best way to run the
power wires to the reverse lights. It ia important to use the Reverse
lights and not the License Plate illumination lamp or any other. Tbe
system is designed to come on when the vehicle is in reverse gear
only. Improper installation can cause the system to not work or to run
at undesired times.
Note: Ail vebieles are designed differently. We offer some general
installation advice here* but check and rc«check you iDStallalion before
starling. Some vehicles may have the license plate on the tailgate and the
Reverse lights may be located on the vehicle pillar. In this case you will
need to study your vehicle closely to determine the best route for the power
wire. In some vehicles you may need to eatend the power wire to reach the
reverse lamps. Power wire can be purchased at an auto parts store or
hardware store if this is needed. Most installations can be completed by
running the power cable behind the trunk or tailgate rubber gasket, tucking
it under the interior trim panel and either connecting at the back of the
reverse lamp in the trunk or removing the reverse lamp assembly (the same
procedure as required to replace the light bulb).
2. The camera cable can be routed as recommended above or
through an existing wire grommet to reach the interior of the vehicle.
If an existing grommet is not available to use. you can drill a bole
behind the license plate to access the vehicle. Purchase a rubber
grommet from an auto parts store to protect the wire from tbe sharp
edges of s bole if you drill one.. The rubber grommet must be a
minimum of 13/32* to allow tbe wire and fuse holder to pass through
it.
Be sure to check behind the intended drilling location before drilling
to ensure no wires or mechanisms interfere or could be damaged
during drilling. Check for interference with license plate lights and
the hatch release switch or mechanism. If not using an existing
factory grommet, drill a bole to match the rubber grommet size that
you intend to use (13/32* minimum) at the selected location near the
vehicle's rear license plate. Route the camera cable connector
through the grommet and insert the grommet into the hole to prevent
water from entering into the vehicle.
3. Now leave enough wire to route behind the license plate. Place the
license plate over tbe opening and line up the holes. Fasten the
camera mounting bracket and the license plate to the vehicle. Use
either the lower mounting holes or the upper on the license plate
making sure that you do not block any information on your plate that
is required by your state laws to be shown.
4. Continue to run the power harness for tbe camera to the vehicle's
reverse lamp. NOTE: Ifthis isa veryshortdistance.be sure to extend
the power cable that comes attached to the camera completely. The
antenna for the camera is located in the harness.
5. Locate the reverse lamp to the tail light assembly. Generally the
Positive wire on the reverse lamp will be a colored wire and the
Negative will be a Black wire. If you would like to insure the wires
are correct; with the vehicle on a level surface, first engage the
emergency brake on the vehicle and place blocks behind the wheels.
Make sure the car is not running but the ignition is switched on and
have another person engage the brake pedal, shift into reverse and
insuring your safety, check the wires with a test lamp. NEVER
ATTEMPTONAHILLORGRADE.
Once you have confuaicd the po»iiivc and negative conncetioa point,
place the vehicle in park, shut off the ignition, and proceed.
