Installation and Wiring
IMPORTANT:
(a)
Read this manual thoroughly before proceeding to installation. You can also have the system
installed by a professional installer such as your local auto mechanic/auto electrician/car stereo store. (b) Turn off
the engine and ACC during installation. (c) Double check that the wiring is correct before power on the system. (d)
During installation, avoid flatting, perforating, cutting, and extending the wires of sensors to reduce unnecessary
signal loss.
1. Installation of the Main Control Box
a)
Find a flat and clean surface inside the vehicle or underneath the vehicle close to the driver's side taillight
assembly as the waterproof main control box gets its power from the back up light and has all the rear
sensors plugged into it. Keep it away from areas of high heat, high humidity, direct water contact, direct
sunlight, and electromagnetic devices.
b)
Place the main control box in place temporarily without securing it to the vehicle as you may need to adjust
the location of the main control box slightly while wiring.
c)
After completing all wiring, use the 2 screws included to secure the main control box to the vehicle. You will
need to drill two 1/8
”
holes through the mounting surface corresponding to the two screw holes on each side
of the main control box.
2. Installation of the Wireless Digital Distance Display
a)
Find a place for the wireless digital distance display on top of the dashboard where the driver can see it
easily. Place the wireless display in place temporarily without securing it to the top of the dashboard.
b)
After completing all wiring, secure it with the included self-adhesive on bottom of the display bracket.
3. Wiring - Power Supply to the Wireless Digital Distance Display
a)
Insert the 3-pin mini plug of the power cable of the Wireless Display into its socket on back of the display.
b)
Locate the +12V (or +24V) and the (-) negative wires from the reverse gear for the back up lights under the
dashboard or near the reverse gear.
c)
Strip 1/2" of the wires found.
d)
Connect the red wire of the power cable to the +12V (or +24V) wire (Fig. 4).
e)
Connect the black wire of the power cable to the (-) negative or chassis ground (Fig. 4).
f)
Wrap the connections with vinyl electrical tape.
Note:
You can also connect the red wire to the ignition switch or ACC. But connecting it to the reverse gear or
back up light is better as the display only needs to work when the vehicle is put in reverse.
4. Wiring - Power Supply to the Main Control Box
a)
Plug the BNC type connector of the power cable of the Main Control Box into its socket on the left side of the
main control box labeled POWER.
b)
Locate the +12V (or +24V) and the (-) negative wires from the back up light near the taillight assembly. If
necessary, remove the taillight assembly to locate them.
c)
Strip 1/2" of the wires found.
d)
Connect the red wire of the power cable to the +12V (or +24V) wire (Fig. 2).
e)
Connect the black wire of the power cable to the (-) negative or chassis ground (Fig. 2).
f)
Wrap the connections with vinyl electrical tape.
5. Installation of the Sensors
IMPORTANT: (a) To avoid false alert from the system detecting the ground, the sensors should be mounted
between 20" to 32" (50cm to 80cm) above the ground and the face of the sensors need to be vertical or slightly
upward angled. (b) Horizontally, the sensors should be equally spaced if possible or symmetric to the center of
the bumper. (c) The outer two sensors should be mounted about 5.9" (15cm) from the corner of the bumper for
better corner coverage.
a)
Refer to Fig. 1 for mounting height and position of the sensors.
b)
The four (4) sensors supplied with this system are under bumper type (each sensor is pre-fitted in a sensor
bracket with two screw holes for easy under bumper installation). Under the bumper, with chalk or marker,
mark the position of sensors, then the two screw holes corresponding to the two screw holes on each sensor
