H. CAREFULLY remove sensors from plastic housing by gently pulling the
top and bottom tabs, indicated by blue circles (Ref. Figure 8a), away as
sensor is pulled out. Do not push on front of sensor as this will damage the
membrane. Place sensors face up in a safe location.
I. Remove plastic housing from OEM bumper by depressing the four
plastic tabs around the inside and pushing housing out. All sensor
housings will have to be placed into the Fab Fours bumper in the same
location as they were removed from OEM bumper. (e.g. Outer right sensor
clip must go into the outer right sensor hole in the Fab Fours bumper.)
