Mounting the Camera:

The camera has two basic mounting options:

The camera 1. (figure 1) can be mounted inside a 1 ¼” (figure 2) or 2” (figure 3)
hitch receiver tube. Slide the camera assembly into the hitch tube. The magnet
in the camera base will hold it securely in place, however the plastic guide on the
camera bracket will help line the assembly up with the hitch pin opening and allow
a standard or locking hitch pin to be used for additional security.

The camera can also be mounted to any metal surface using the magnetic base. 2. (figure 4)
The soft pads on the base will prevent sliding or scratching and the camera bracket can
pivot up to 90° to allow the field of view to be adjusted.

Connecting the Camera:

CAMERA POWER CONNECTION

The camera is powered by plugging the camera connector into the vehicle’s towing plug.
The camera has a 4 position connector which will attach directly to many vehicles and
has a pass-though design that will allow it to be plugged between the vehicle and trailer.
Some vehicles may need a 7 position to 4 position adapter (figure 5) which is not included.

NOTE: A commonly available 4 position tow wire extension (not included) will allow the
camera to be mounted farther away from the vehicle plug for gooseneck or fifth wheel
trailer hitching up applications.

Notice: Depending on the make/model of the vehicle the running lights or headlights
may need to be turned on to power up the vehicle’s tow plug.

Connecting the Monitor and Antenna:

ATTACHING THE ANTENNA

The wireless antenna (figure 6) attaches to the threaded connector on
the back of the monitor (figure 7). Once attached, it can be rotated 360°
as needed to find the position which give the best reception from the camera.

MOUNTING THE MONITOR

When choosing a location to mount the monitor (figure 7), make sure the monitor
is in an area that will not obstruct your vision while driving or interfere with access
to any of the vehicle controls. It can be placed on the windshield using the mounting
arm (figure 8) or clipped to an air vent (figure 9). Both options use the mounting slot
(figure 7) on the back of the monitor.

Temporarily place the monitor stand or clip in the location that you have chosen 1.
and route the power cable (figure 10) to the vehicle’s 12V power outlet and verify
the cable does not interfere with the safe operation of the vehicle or access to
any vehicle controls.

To use the mounting arm, slide it into the mounting slot 2. (figure 7) and remove the
vinyl protector from the base, place it firmly on a smooth surface and rotate the
small cam near the base of the arm.

To use the vent clip, slide it into the monitor mounting slot 3. (figure 7) and gently
press the clip and monitor over the vehicle air vent fins.

POWER CONNECTION

Insert the small DC plug 1. (figure 10) of the power cable into the right side
of the monitor (figure 12).

Insert the larger 12 Volt power plug 2. (figure 10) into the vehicle power socket.
The red LED (figure 11) will come on if the vehicle socket has power.

Notice: Depending on the make/model of the vehicle the ignition may
need to be turned on or to the accessory position for the 12V socket
to have power.
