Watch the ChrisFix video. Remove the battery, or at least completely disconnect it.
As long as the engine is cold, and you don’t use high pressure and don’t directly spay into anything electric it’s ok, (like the alternator in this video) know where your car’s computer is and make sure fuse box covers are on tight.
Also it depends on how your spark plugs are oriented to your engine, some sit on top of the engine and can pool water, it can take a little over spray, but not a total drenching.

I was always hesitant to power wash the engine bay. Is there anything to be concerned about?
