Factory Wiring For Trailer Harness?

My truck didn't come with tow package. Before doing my own wiring, I'm trying to find out if non tow package trucks have an unutilized wire connector for it. I've noticed a few unplugged wire connectors in various parts of the truck, cold any of these be what I'm looking for?

 

There's a hidden connector behind all the other ones at the Driver's kick panel. That would go to the Towing converter. From there you'd need the mating harness to the rear bumper. This harness only provides ground, parking and the combined stop and turn. For the rest of the missing 7 pin towing connector you will need to add Reverse, trailer electric stop control and trailer battery charging circuit.
