I picked up a truck from an auction. It's an F250 V8 twin-turbo Diesel that was used as a people-hauler. It looked like this about two-months ago. So it had a few mods done to it. Suspension, fuel tank, interior and some moarz. I haven't had an issue with it at all, but what in the hell is this thing? It's found just behind the front bumper. It connects to this cable, which then goes up into the engine compartment. I'm thinking that because it's a diesel, border patrol may have used it to charge the batteries to keep them topped off or to jump them in-series.
