Begin by attaching the sensor mounting bracket to the
Bumper face, making sure the locking tabs get into place when inserted. After that, fit the O-ring spacer completely around the sensor membrane overhang, making sure the wider part touches the sensor's main body and the narrow end sits on top of the sensor's protrusion and at the back. Situate the sensor to make sure it's held by the sensor bracket on the back of the bumper, so that the latch on top and bottom are below the tabs on the sensor and the sensor membrane rests flat against the bumper body. SEE Help. Last, attach the wire harness connector to the sensor connector receptacle and link the battery negative cable once again.
