UPDATE: followed the wires the green ones from switches is seen in picture connecting to different blocks with 4 prongs each. The other photo I don't know what that part is or why the red wire is cut....

So the green wire is hooked to a pair of relays.
A better picture of the label on the box in the first picture would be good. Looks like maybe some sort of pressure switch. Trailer brakes maybe.
