What is this used for?

Good day everyone. Just picked up a new to me 2020 F250 Super Duty. I’ve looked in the owners manual with no success to what this is for? Is there something that is supposed to fit in the socket?

Think it to be a rather small coin holder

That is a coin holder. I know… ridiculous.

It is also the place a factory brake controller would be installed for towing trailers that have electric brakes.
