think those are some kind of sensor maybe

Your right. I've since learned they are temperature sensors. The one on the left sends the data signal for the outside ambient air temperature to the temp display on the interior rear view mirror. The other one is a temp sensor also, but for what I don't know.

Are you sure none of these are airbag sensors?

Actually likely not airbag sensor. Just looked at mine. Since it is attached to a flimsy piece of plastic, and not front bumper.

that is waht my mechanic said he thought they were, we are wondering where the airbag sensor is, because my air bag message light is on, we think it may have been brushed accidentally when installing HID lights, anyone know where it is???

I think they are Airbag Sensor's. If you really want to find out just unplug them and stick a mulitimeter in them and see what happens.

wrong. They are power for your horn. I had a air horn for a bit and had to disconnect them because it would blow the fuse when hooked up to the factory horn.

Wrong again! Let me set this straight. The gray things that are on the end of the blue plugs are temperature sensors. The outboard one (the one on the left in the photo) sends the data signal for the outside ambient air temperature to the temp display on the interior rear view mirror.

You can prove this for yourself by disconnecting the gray sensor from the outboard plug, and you will see the temp display on the rear view mirror no longer displays the temp, but displays an error message "OC" instead.

If you then take the gray sensor from the other plug (the one on the right), and plug it into the plug on the left (swap them in other words), the temp display on the rear view mirror is working again. Therefore they are both identical temp sensors.

The inboard one (on the right in the photo) is there so the HVAC PCM knows what the ambient air temperature is, i.e. for the heating and air conditioning. I've verified this in the factory service manual (page 1-151). So... there it is.
