I need some help on replacing this thing. Bought a used one and got it in the mail today. Went to put it in and aren't really sure if it's the right box. Is the turn signal box down by the driver's side kick panel that says FCO1 on it? How do I replace this thing? What plugs do I pull, etc. etc.? I know this should be easy but what I got in the mail doesn't look like the FCO1 box at all. Thanks.
