I can post a pic if necessary but I have a feeling someone will know what I'm talking about. I've always wondered what that "box" is located in the rear of the vehicle and above/behind the spare tire. It's supported by a piece of metal that in my case is so rusted out that this "box" is now hanging down and I had to temporarily support it with wire. There are electrical wires and plugs connected to it and my best guess is that it has something to do with the fuel system, but I have zero clue. Anyone know ?
