the contents of the shipping package and verify the following items are included: 
 

Antenna Sensor (1)  
Display Unit (1)  
Interconnect Cable (1)  
User Manual/Operating Instructions 
Sensor Stainless Steel Mounting Hardware 
 

(3) 1-1/4” x 10-24 Bolts 

 

(3) Hex Locking Nuts 

 

(3) Flat Washers 

Display Mounting Hardware 
 Mounting 

Bracket 

 

(2) #4-40 Lock Nuts 

 

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.
