What are these harnesses?

Please help me identify what these harnesses could be. Clearly I'm prewired for something and I'd love to know what so maybe I can make my truck that much better.

In the first image its the black harness, the white one is for my led drl.


The second and third images its the black harness inside the left front fender.



Thanks for the help. The images rotated for some reason. They should be oriented 90 turn from left to right.

 

What is your year and trim level? Might be related to fog lights if you don’t already have them.

 

I have a 2017 SR5 XSP, definitely not the fog lights as I have them as that's what I was in there to do was change the fogs and headlights.

 

Nobody knows or has an idea on how to figure this out?

 

Is it just the one black rectangle connector at the front left of the truck near the core support? 3 wires I think?

99% sure it’s the connection for the front sonar/parking sensors. Another one just like it will be on the right rear near the frame rail behind the tail light.

A front and rear sun harness attaches here to go to the parking sensors in the front and rear bumpers
