If you have automatic air conditioning, the sensor and wiring are already on your vehicle. If you have manual air conditioning the sensor will not be there, not certain about the wiring. The factory sensor mounts behind the grille on the support bar slightly to the passenger side of center. The illustration below shows as if you are looking at the front of the truck with the grille removed. If the wiring is there you will find a two wire connector taped back to the harness. The wire colors will be light green/black and dark green.
Connector looks like this:
Ya I dont see any thing right up by the grill area. Do you know if the harness that runs to the sensor comes from the drivers or passengar side of the truck.I'm wondering if its not tied back in the harness some where. I wonder if I can go to GM and buy the harness for the temp sensor? Thanks again for the help!
