Correction

Relocate the ambient air temperature sensor.

5. Cut the terminals off and splice 206 mm (8 in) of wire to the harness.

6. Install the connector with new terminal and seals.

7. Install a piece of conduit on the new harness.

8. Install the connector to the sensor and install the sensor from the back side of the brace.





9. Install conduit on the added wire harness and use two tie straps to fasten the harness to the side of the front end radiator support brace as seen in illustration above.

10. Install the grille.
