So from what I can tell online and from a few friends is that my TEMS means I have electronically controlled suspension or something? I have no Idea but either way this thing sits higher then my last one and I hate it. Also when I was installing my tail lights I found this box thing that I have no clue what the hell it is and Im still wondering what the hell these two wires are on the back of my tail lights, Anybody else know?
