On the 3.7 the air box has a drain....not sure about a CRD...
If you mean the little 1/4" hole at the bottom that's exposed down to the inside of the wheel-well by the radiator, yep, it does.
With respect to protecting the electrics in the engine bay, I usually hand-clean the major electric items with some disposable wipes then put a small sandwich bag or a plastic grocery bag over each and wrap a little tape around with with the bottom facing down (as much as possible). That keeps 99% of the water out and it's a cheap, fast, and easy way to protect the electronics. As for the sensors and other plugs that have gaskets in the connectors, they're designed to resist moisture and usually sealed with dielectric grease (or they are after the first time I open and re-close them, hint, hint.) so don't sweat them too much and just avoid putting a direct high-pressure spray on them.
If you do get water into a sensor connector (the diagnostic codes will tell you which one
), a little wd-40 will clean the contacts and prevent corrosion (then go seal the plug with the grease when you're done). In fact, the WD-40 is probably a good thing to use on the tough spots of the CRD anyway. I've found murphy's oil soap gets diesel residue off pretty well without being too harsh. That's taken the place of gojo at my house next to the washroom sink.
