2. Choose one of the following mounting methods for your vehicle
a. Use the sensor sleeves provided to compensate for contours in the
vehicles bumper.
b. If the surface is 90- 95 degrees perpendicular to the ground, install the
sensors directly in the bumper (see Figure3).
3. 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.
4. Drill the sensor holes.
o When using the sensor sleeves, use a 28mm hole saw (part# AS-
28MMHS). Drill at a perpendicular angle to the bumper (see Figure 2).
o When installing the sensors directly in the bumper, use a 22mm hole saw
and drill at a perpendicular angle to the bumper (see Figure 2).
o When drilling a metal bumper, remove the sharp edges using a round metal
file. Be careful not to enlarge hole when filing.
