guy in a forum posted this question:
"I asked this question on most of the Mustang websites when I had my '03 GT and nobody knew what they were. I've asked the local Ford parts guys and they have no clue. I've looked thru the Service Manual and can't find a mention of them anywhere. Now I get a new Cobra and I see they are on this car as well. I'm talking about the little black box directly behind each rear tire in the fenderwell. There is one on each side, they have no wires running to them, so I'm stumped. What do they do??"
anybody here know? ive often wondered myself. i dont think that my 96 had them
thanks in advance for any feedback
