Marking and Drilling Holes
Figure 1
1. Mark the locations for the sensors on the rear bumper using a grease
pencil.
a. Identify the sensors height on the bumper and mark. The sensor
height should be between 18” and 30” from the ground.
b. Divide and mark the bumper as shown in Figure 1.
c. Install the sensors equally from the center of the bumper, as shown
in Figure 1.
d. Inspect behind the bumper where the sensors are to be located to
check for possible obstructions, including metal braces, electrical
wires, and clearance. The sensors need 1.3” of clearance behind the
bumper to be fully inserted and mounted securely. Do not mount
sensors directly above exhaust pipes. Relocate the sensors if any
obstruction exists.
2. Before drilling the holes, use a center punch to make a dimple on the
bumper to prevent the drill from slipping from the intended mark.
3. Drill the sensor holes.
o Use a 26mm Hole Saw if you are using a sensor sleeve
o Use a 13/16” Hole Saw if you are installing without a sensor sleeve.
NOTE: Drill bits available for purchase from Audiovox.
o When drilling a metal bumper, remove the sharp edges using a round
metal file. Be careful not to enlarge the hole when filing.
