INSTALLATION
INSTALLING THE SENSORS
The CA-5009.II can be installed with (2) sensors or (4) sensors on the rear bumper of the
vehicle. (4) Sensors are recommended for the best coverage behind the vehicle.
1. Measure out the distance across the bumper and try to space the sensors equally apart.
Space the sensors at least 1 -1.5 feet apart from each other if you are installing (4)
sensors and 2-2.5 feet apart from each other if you are installing (2) sensors. The height
of the sensors should be at least 1.5 – 2.5 feet from the ground to the sensor but no less
than 1.5 feet. (See FIGURE 1) If your measurements come in a little over the specified
height or width than that’s fine just as long as the sensors are not space too close
together or too close to the ground.
2. For trucks with uneven bumper space such as pick-up trucks with a center step or and
license plate in the middle, you can space the sensors evenly on both side of the center
step in the bumper. (See FIGURE 2) Some truck bumpers may be a little higher than 2.5
feet. This is not a problem and will not inhibit the system from working. The kit comes
included with plastic mounting shims which will angle the sensors down a little bit if you
have to mount them higher up on the bumper. For trucks with metal bumpers, we
recommend using a kit called the CA-5009.II.MBS. This system is the exact same but
comes with sensors specifically designed for use with metal bumpers.
NOTE: Use masking tape or electrical tape to mark your measurements on the bumper for
the sensors. Make sure that your measurements are straight all the way across the bumper
and that the sensors have been spaced evenly before you begin drilling.
3. Use the provided hole saw bit to drill the holes in the bumper. This hole saw bit should
give you an adequate sized hole to fit the sensor perfectly. Once you have the holes
drilled, route the sensor cables through the holes and snap the sensors into place. (See
FIGURE 3)
NOTE: If the sensor fits too tightly into the hole then try to drill the hole just a little bit wider
but not wide enough to where the sensor is very loose. If the sensor is too tight, the system
may not function properly. If the sensor is loose, DO NOT apply any kind of adhesive or
silicon to hold it in place. See our troubleshooting section for more details.
4. When placing the sensors into the bumper, it is important to note how they should fit into
place. Always try to put the sensors on the flattest part of the bumper surface aiming
straight out behind the vehicle. If the sensors are angle slightly downward on the bumper
than that is okay just as long as they are not angled extremely up or down in direction. If
the sensors are angled too far downward, then they will pick up the ground the system is
on and cause false warnings. If the sensors are angled too far upward, then they will not
pick up anything because they are aiming at the sky and this will cause the system to fail.
NOTE: If you run into an issue during the install where you need the sensors to be angled
back up or down or the bumper surface is slightly curved or uneven, then you can use the
provided plastic shims to angle the sensors the way you need them or to compensate for the
uneven bumper surface. (See FIGURE 4)
