Identify sensor

Can anyone tell me what and where this goes? I have changed water pump and while putting it back together I can’t remember where this came from. It was left hanging beside the rad.

That’s the ambient air temperature sensor. It goes on the power steering cooler line

It clicks into the slot. You’ll know it when you see it

That’s a pic from the internet but it goes into a slot that looks exactly like that in the power steering line running on the front of the radiator on the bottom
