I bought an 2020 X-town 300i a few months ago. The left mirror arm has become loose enough that I can move it. I lifted up the rubber cover and found a wire wrapped around in such a way that I'm worried if the mirror moves completely around it will break the wire (the turn signal is in the mirror). So what I need to know is how do I tighten this mirror so this doesn't happen. It has a nut of some sort that I've never seen and I don't have, or know, what kind of tool to get. Can anyone help???
