These instructions do not apply to all vehicles. They are meant as only 
as a general guide due to the number of different makes & models. For 
vehicle specific questions, contact your vehicleʼs manufacturer.
Monitor Installation
When choosing a location to mount the monitor, make sure the monitor is in an area that will 
not obstruct your vision while driving. It can be placed on the dashboard, or on the windshield 
depending on the angle.
1. Temporarily place the moni-
tor stand  in  the  location that 
you have  chosen. Make sure 
the driverʼs vision is not  ob-
structed in any way or any of 
the vehicleʼs 
2.  Route  the  monitorʼs  power 
cable  to  the  vehicleʼs  fuse 
block/box or cigarette lighter 
socket/12V power outlet  de-
pending on the cable you are 
using
3.  If  you  are  satisfied  with  the 
location  of  the  monitor  and 
the  cable  route  you  have 
chosen, attach the monitor or 
stand with the supplied Velcro.
MONITOR POWER CONNECTION
There are two ways to supply the monitor with power, one uses a 12 Volt cigarette lighter 
adaptor plugged  into  the  vehicleʼs cigarette lighter socket, and the other uses  a  wiring 
harness hard wired to the vehicleʼs fuse box.
12 Volt Cigarette Lighter Adaptor Using the Monitorʼs ON/OFF Button
1. Choose a route for the cable from the monitor to the cigarette lighter socket. It can be a direct 
route with the wire exposed or a route around the dashboard hidden under the vehicleʼs inte-
rior trim. When using a direct route for the power cable make sure the power cable is secured 
and will not interfere with the operation of the vehicle. When routing the power cable behind 
the vehicleʼs interior trim be careful not to cut the wire on and sharp edges or pinch and dam-
age the cable when re-installing the trim.
2. Plug the end of the power cable into the monitor, 
3. Plug the 12 Volt cigarette lighter adaptor into the cigarette lighter socket.
4. Press the ON/OFF button to turn the monitor.  
Hard Wired to Fuse Box Using the Monitorʼs ON/OFF Switch (Fig. 1) 
1. Remove the negative battery cable from the vehicleʼs negative battery terminal.
2. Remove the fuses from both of the in-line fuse holders.
3. Connect the Red wire to the 12 Volt +/ACC terminal in the vehicleʼs fuse box. See vehicleʼs 
ownerʼs manual for fuse box diagram. 
4. For the ground cable locate an area of metal on the vehicleʼs body/firewall that does not have 
any vehicle components behind it. Sand off any paint to reveal bare metal, this area will be 
your chassis ground.
5. Drill a hole for the supplied self tapping sheet metal screw. Make sure there are not any ve-
hicle components on  the other side of where you are drilling the hole.
6. Attach the grounding cable to the chassis ground with the self-tapping sheet metal screw.
7. Plug the power cord into the monitor.
8. Press the ON/OFF button to turn the monitor. 
Automotive video equipment installations can be difficult at times, even to the most expe-
rienced of  installation  technicians.  If  you  are  not confident  working  with electrical  wiring,

7.   If you are going to drill a hole, choose a location as close to the camera where the power 
cable comes out of it. BEFORE YOU DRILL A HOLE YOU MUST CHECK AND SEE 
WHAT IS BEHIND WHERE YOU ARE DRILLING
.
If there are any vehicles compo-
nents, such as electrical parts or fuel system components behind where you are drilling, 
you must take whatever precaution is necessary not to damage them. Remove the license 
plate and camera before drilling.
8.   After you have drilled a hole, insert the supplied grommet(Fig.5), then pass the power 
cable through the grommet into the vehicle (Fig.6). You must use the grommet to prevent 
the metal edge of the hole from cutting the power cable.

10. Once  you  have  located  the  reverse  light  circuit 
you will have to route the cameraʼs power cable to 
that location. You must sucurely fasten the power 
cable to prevent it from being caught on any ve-
hicle component  such  as the  trunk  hinge. Never 
route the cable on the outside of the vehicle.
11. The sockets for most vehicleʼs reverse lights have 
two wires connected to them. One is positive and 
one  is  negative,  to  determine  which  is  positive 
you will need at least a 12V test light available at 
any auto parts store,  or a multi-meter. Using the 
test light, attach the negative lead to a spot on the 
vehicle that has a chassis ground, with the reverse 
light on touch the other lead to one of the wires on the reverse light socket. When you 
touch one of the wires and the test light comes on that wire is the positive wire, if the test 
light doesnʼt come on, that wire is the negative wire. 
12.  After determining which wire is the positive and which is the negative, turn off the igni-
tion key, then remove the batteryʼs negative cable. 
13.  Following the Scotch-Lok® instructions, splice the one end of the in-line fuse holder 
using the supplied in-line Scotch-Lok® wire connectors to the reverse lightʼs positive(+) 
wire, then splice the red wire of the cameraʼs power cable to the other end of the in-line 
fuse holder. 
14.  Next splice the black wire of the cameraʼs power cable to the  reverse lightʼs negative(-) 
wire. Secure all wires with cable ties or electrical tape.
1. Reattach the vehicleʼs negative battery cable.
2. Reinstall the in-line fuses.
3. Turn the ignition key to the accessory position, do not start the vehicle.
4. Engage the parking brake, then put the shifter in the reverse position.
5. Turn the monitor ON by pressing the ON/OFF button on the monitor.
6. Look at the monitor, if the image does not match your rear view mirror press the top button 
on the monitor to correct the image.
There are four different views for the monitor, each time the button is pressed the image will 
change.
These different views allow you to mount the camera and/or monitor either right side up or 
upside down and still display the image correctly on the monitor.
After testing the unit and you are satisfied with the route you have chosen for the cabling, you 
must permanently install it.
Fully tighten the license plate bolts.
Route all wires behind interior panels or under carpeting so they are hidden.
Use supplied cable ties to neatly gather all excess wire.

CAMERA WIRING DIAGRAM
1.  Remove  the  license  plate  bolts/screws  from  the 
rear license plate. (Fig.1)
2. Put the license plate bolts through the holes on the 
cameraʼs mounting bracket.
3. Place the supplied wedges over the bolts, then put 
the  bolts  through  the  holes  on  the  license  plate 
that will line up with the holes on the vehicle. The 
wedges should angle the camera down. (Fig.2)
4. Temporarily tighten the license plate bolts/screws.
5.
The cameraʼs power cable will have to be routed 
through the  vehicleʼs body  to  an  area  where  the 
reverse light circuit is. Some vehicleʼs may have a 
hole available to pass the wire through, you can use an existing opening 
(Fig.3)
 like where 
a license plate light is mounted, or drill a hole close to where the power cable is attached 
to the camera. 
(Fig.4)
CAMERA INSTALLATION
You  may  mount  the  camera  using  the license  plateʼs top  or bottom  mounting  bolts  or 
screws. When  mounting  the  camera  you  must  make  sure  that  itʼs  field  of  view  is  not 
obstructed. Depending on the vehicle, you may mount the camera on the top or bottom 
of the license plate. To adjust the angle that the camera is mounted to the vehicle use the 
supplied wedge shaped shims.

6.
If you able to use an exsiting opening tighten the license plate bolts, then route the power 
cable into the vehicle. Skip the next two steps.
9.   Next youʼll need to find the vehicleʼs reverse lights. Turn the vehicleʼs ignition key to 
the accessory position, engage the parking brake and put the car in reverse. Look at the 
vehicleʼs tail lights to see where the reverse lights are located. 
  To locate the reverse lightʼs 12V+ wire it will be necessary to gain access to the rear of 
the vehicleʼs tail light. 
  For help locating the vehicleʼs reverse light circuit contact your vehicleʼs manufacturer 
for vehicle specific wiring diagrams.
