So I did a stupid thing and backed over a curb that I had no idea was there and in the process, the little black box that sits between the two mufflers is hanging from the underside of the car. First, what the heck is it and what does it house? Two, do you think it is easy to fix or should I not chance it and have Ford look at it. It looks like there are screws that were used to attach but obviously these snapped off, but not 100% sure. Any help or guidance would be great. It is a 2014 convertible mustang.

 

If it's before your axle, it's prob the plastic cover for the gas tank...
If it's any further it's your differential cover, and THAT would be bad!

Kinda hard to tell what it is w/o a pic or 2

 

Since he said "black box that sits between the mufflers" it isn't the differential cover or the gas tank.

More than likely it is the emissions electronics box that sits right under the spare tire well. Is everything plugged in still, and are you getting any codes? You probably just pulled it loose from the mounting pegs.

 

Yes it seems everything is still plugged in and I'm not getting a check engine light or codes.

 

Then you probably just broke the pins that hold it in place. I don't think it has screws, but I haven't really had any reason to look closely at it either.

 

Pictures would be a huge help...but it seems like Jim has you on the right track.
