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 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. This can be done by applying
power to the system with the sensor in the proposed location 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 9/32” (7mm) holes centered at the marks. (CHECK THESE DIMENSIONS)
4. Secure the sensor to the vehicle with the three supplied 10-24 UNC bolts, washers and
nuts or equivalent. Apply a maximum torque of xx 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.
