Dielectric grease in/on/around connectors??

I’m working on installing a set of aluminum skid plates on my Rubicon. While taking the factory ones off I noticed a bunch of connectors.

SOOO that got me thinking what’s the best way to seal them?? A little dab inside the connectors? Fill the connectors? Just running a little bead around the closed connector? I have no intentions on going deeper than the tires but I’ve also fallen into a hole a time or 2 and would like to stay proactive in case things get deep.
