Can anyone give me a hand? I bought an used trailblazer and looking under the hood near the fuse block, there's a red wire that's loose, seems like it belongs on a post(which is empty) not even a nut on it. Just wondering if anyone can take a look at theirs and confirm. I've attached a pictures, i've highlighted the red wire (red), and the post/stud yellow, let me, if the red wire belongs on the yellow post. Thanks!!!
