This was on the second photo...Definitely for towing. Wiring harness connector on the right for brake lights, running lights and turn signals, etc..
The part on the left turns out to be a break-away switch. A cable would attach to the pull ring and activate the braking system, should the unit being towed separates from the tow vehicle. I have no idea how it would be set up to work on towing the Jeep... But that is what it is.
