I accidentally drove over a tree stump and pulled the complete inside of my wheel well from the drivers seat off of the underneath of my van - also a plastic black box broke into pieces. I had to have a tow truck tow my van to the mechanics, and I scooped up all the broken pieces of plastic to see if they could identify what it had been. They were able to put the under-coverings back up into the wheel well and fix my bumper but they had no idea what the black box had been for and they threw the pieces away. Does anybody know what this box was for, what it was and do I need it??
