I found - What is it?

[Axcontrols]

While rooting about under my car (2003/53 ML 270 CDI) I found this piece of plastic resting on top of a front/left hand chassis/box section. I posted it in electrics because I kinda feel it's a cover for something.
Any ideas?
Thanks Guys.

Top of a fuse holder , or Sam/ecu type thingy ?

According to Google it's a connector cover for a Chrysler 300, though as it shares the engine could be off yours.

I did google the part numbers before asking here and found dozens of parts that look nothing like my part. But your link does help. Thanks
