Have you ever opened your hood right after driving in a rain storm? Have you ever looked under the hood right after a nice water crossing or water hole?
If you did, then you would see that most everything under there is wet.
Start with a hose. Soak all the mud. Keep coming back and wetting it more every 10 minutes or so. After a couple soaks, most of the mud will fall away. Wash the rest down with a soapy rag and rinse again.
Don't shoot strong streams of water into any obviously bad places (intake tract, electronics, etc...) and you should be fine.
Right after you finish, fire up the jeep and go for a ride to heat and dry everything out.
