8. Remove a suitable amount of wiring harness insulation as required to access the wiring.

NOTE:

Cut only one wire at a time and stagger each joint to allow easier installation.

NOTE:

The colors of the overlay harness wires may vary.

NOTE:

Vehicles with adaptive damping have six (6); wires, vehicles without adaptive damping have three (3) wires.

9. Cut the wire on the vehicle harness leading to cavity one of the height sensor connector in a suitable position and remove 10mm of insulation.

(For connector location and pin identification, see Appendix 1 and refer to the relevant connector in the relevant Electrical Library).

NOTE:

Make sure that the heat shrink is installed over the wire before crimping the connection.

10. Using a suitable tool, crimp the connector to the height sensor harness.

^ Position the heat shrink over the height sensor harness.

NOTE:

The overlay harness should be cut so that there is no additional length added to the overall harness length after the repair.

11. Using a suitable tool, remove 10 mm of insulation from the appropriate wire on the new height sensor harness connector.

CAUTION:

Make sure that the surrounding components and trim are suitably protected when using the heat gun; failure to follow this instruction may

result in damage to the vehicle.

12. Using a suitable tool, crimp the connector to the appropriate wire on the new height sensor harness connector and secure the heat shrink.

NOTE:

Cut only one of the wires at a time and stagger each joint to allow easier installation.

NOTE:

Vehicles with adaptive damping have six (6) wires; vehicles without adaptive damping have three (3) wires.

13. Carry out steps 9 - 12 for the remaining wires on the height sensor connector.

14. Using a suitable tape, insulate the height sensor harness.

15. Connect the height sensor electrical connector.

16. If required, secure any wiring harness clips released for access.
