Hey guys and gals. I found two thing rubbing on my serpentine belt today and was hoping for some help identifying both an electric connector that seems to go to or near the power steering pump as well as the nut/stud circled. Trying to remove the nut from the stud but the stud came out instead. I stopped shy of unthreading it all the way as I have no idea of possible repercussions. It looked to just be for the cover/bracket that bolts to it but would rather ask someone knowledgeable first. I’ve circled both in the picture below. Any help would be greatly appreciated!
