For the right-hand sensor, a cutout must be made in a guide (1) in the foam to enable the connector to be connected.
- Use a knife to cut out sufficient material to enable the connector to be connected to the sensor
- Install the right-hand sensor and connector. Check that the connector can be connected
- Leave the sensor and connector in place.
- Connect the wiring harness connector to the sensors.
Note! A click should be heard when connecting, indicating that the connector lock is engaged.
