Sensor/Antenna Location
The PreView
tm
sensor mounting location is key to proper system operation. Ideally the sensor
should be mounted on the rear center of the vehicle at roughly 36” (1M) +/- 12” (0.3M) above
the ground. The sensor face should be perpendicular to the ground. Select a location that will
provide some protection from impact and debris while allowing an unobstructed view of the
target hazard area.

Before the PreView
tm
system is permanently installed to the vehicle, verify that the selected
sensor mounting location provides a clear detection zone. Temporarily attach the sensor in
the proposed mounting location, apply power to the system, and verifying that nothing is being
detected.
Sensor/Antenna Mounting
1. Select the appropriate sensor mounting location.
2. The sensor must be mounted with the cable exit either on the bottom (preferred) or top.
3. Using the sensors’ mounting holes as a template, scribe position marks through the holes.
Drill 1/4” (6mm) holes centered at the marks.
4. Secure the sensor to the vehicle with the three supplied 10-24 UNC button head screws,
washers and nuts or equivalent. Apply a maximum torque of 22 inch pounds when securing
the sensor.
Sensor Power Connection
Locate the vehicles reverse light power wire and connect to the red wire on the sensor harness
using 18AWG wire. Connect the black wire of the sensor harness to vehicle ground.
