5. Some vehicles (or trailer) may have a hole available to pass the wire through, such as
where the license plate light is mounted, or you can drill a hole close to where the
power cable is attached to the camera. Once you have chosen where the cable will
enter the vehicle's (or trailer's) body, remove the camera. If you are able to use an
existing opening, skip the next two steps.
6. Before you drill a hole you MUST CHECK and see WHAT IS BEHIND WHERE YOU ARE
DRILLING. If there are any vehicle components, 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.
7. After you have drilled the hole, insert the supplied grommet, then pass the camera
cables through the grommet into the vehicle (or trailer's). You must use the grommet
to prevent the metal edge of the hole from cutting the camera cable.
8. Mount the transmitter box inside the trunk. Connect the camera's power cable and
the transmitter box power cable to the transmitter box.
NOTICE: Choose position to mount the transmitter boxes as close as possible to the
receiver for better signal transmission; The length of the power cables are long
enough for routing from the rear end to the front of the vehicle or trailer.
The transmitter doesn't comply with weatherproof.
9. Next you'll need to find the vehicle's (or trailer's) reverse lights. Turn the vehicle's
ignition key to the accessory position, engage the parking brake and put the car in
reverse. Look at the vehicle's tail lights to see where the reverse lights are located,
they are the white lights. To locate the reverse light's 12V+ wire it will be necessary
to gain access to the rear of the vehicle's (or trailer's) tail light. For help locating the
vehicle's (or trailer's) reverse light circuit contact your vehicle's (or trailer's)
manufacturer for vehicle specific wiring diagrams.
10. Once you have located the reverse light circuit you will have to route the transmitter
box power cable to that location. You must securely fasten the power cable to prevent
it from being caught on any vehicle
component such as the trunk hinge. Never
route the cable on the outside of the vehicle
(or trailer)!
11. The reverse light sockets on most vehicles
have two wires connected to them. Usually
the negative wire is black and the positive
wire is a colored wire. If you are uncertain
about the wiring, you can use a 12 volt multi-
meter available at most auto parts stores to
determine which is the positive wire. Follow
the manufacturer's instructions for the safe
use of the multimeter.
12. After determining which wire is the positive and which is the negative, turn off the
ignition key, then remove the battery's negative cable.
13. Splice the red wire using the supplied in-line wire connectors to the reverse light's
positive (+) wire. Use a set of slip joint pliers to squeeze the TAP and insure good
connection.
14. Next splice the black wire of the transmitter box power cable to the reverse light's
negative (-) wire or ground.
15. Replace the reverse light bulb, and then re-install the light socket. Secure all the
wires with cable ties or electrical tape.
16. Re-attach the negative battery cable to the battery.
