Relay behind rear switch panel

I am fixing one of my rear switches and was wondering what the relay behind the rear switch panel controls? I tried all the switches back there and none make it click. Wondering if it has something to do with the reverse lights.

Looks like this is your first post, welcome to the forum. Sorry, I have no knowledge of what that relay is for.

Update: It is for the reverse light system. When you are hooked to the truck it uses the rear patio light and the two floods on the rear sides for reverse lights. This relay removes power from the switches in the panel. This helps prevent back feeding.
