That little black box has an important black charcoal canister in it.
I found this out the hard way.
I installed a sub inclosure in the spare tire well. The increased vibration caused the weld for the black box to fall off. I heard something scraping on the roadway. It was the black box scraping. I took it to the dealership to have it welded back on. Before I knew it the "master techs" at ford were removing my $7000 stereo from my trunk. They ended up giving me a bolt and a rubber bushing and sending me on my way.
Very important black box.
