Where does this plug into??

[RyanEAS]

In the middle of my AC repair job, and I discover this plug that was detached and I have NO IDEA where it's supposed to go! It is located by the radiator, driver's side. It's not for the headlamp assembly, nor is it for the fan clutch. Ideas? Pictures would be even better!!

That's the outside air temp sensor, plugs in behind the fan shroud.

That's the exterior temp sensor. It mounts in the hole on the shroud just in front of the condenser.

That Blue & Green Harness Connector is the Ambient Air Temperature Thermocouple for sensing outside air thermal changes.... Do you see that "hole" in the fender well on the right side of the image you posted/? If that harness and plug will reach all the way over to it... Plug it in there and see if it looks okay:



EDIT:

Ahhhh... Scooped by "The Man"...even better ....

Thermocouple

Thanks everyone! I was really hoping it wasn't an air bag sensor!! 😳

Usually anything to do with air bags is bright yellow.
