I'm relatively certain that this wire was not here when I had purchased this vehicle about a year ago, but just last night I was looking down for some reason and realized there was this wire hanging. I looked up to see if there were any open ports where I could plug it into but there didn't seem to be any.. and I don't know if this is helpful, but I also noticed that the wire itself was wrapped around what looked like another, larger wire. I'm a lil lost here, my best guess is it was some aftermarket install and hoping it's not a sensor that's randomly unplugged lol, no check engine light on. '12 civic LX 42K
