So I took off my front bumper to paint it and there was a plug of wire of some sort and I dont know what it is. It is just hanging towards the bottom of the radiator. All B5s ive seen has one.

Could anyone tell me what this is?

Thanks for any input you may have!

 

In the middle over the power steering cooler? If so, it's supposed to mount on a small bracket at the bottom center, just above the cooler. It's the ambient air temp sensor for your outside temperature display.
