Might be a dumb question?

I noticed today while running motor I was hearing a clicking sound so thinking it was maybe a lifter but it wasn't but that is a good thing. There is a part on the passenger fender that was doing the clicking. I'm not sure exactly what it is or it's purpose so I thought maybe one of you gentlemen could answer it? I don't remember hearing it clicking before. Thanks

Noise like that on passenger side is usually the dreaded manifold busted bolt holding the heat shield in place which flaps if it busted it's lid .... but on the fender? I never heard that one ...

I didn't title the thread correctly. What I am looking to find out is the black switch or solenoid. I don't remember it clicking like this before so learning what it is and then doing some research to fix it if needed. Thanks
