Dyna 2000 Water resistant?

Trying to decide on where to mount my Dyna 2000 control module. Im building a small enclosure for fuse box, battery and starter relay, but Im wondering if I can mount the Dyna 2000 control module in the open air behind one of the side covers?

Shouldn't be a problem. Mine is held to the inner fender with Velcro, and covered by the tool tray. It gets dusty and damp, but I rarely ride in the rain. When washing the bike down, I cover the end with a clean sandwich bag just to be safe.

VERY CLEAN! thanks for the input.
