Need help to identify cables under dash

I need some cables to be identified. Here are the pictures.
2018 Toyota Tundra Crewmax SR5 4.6 2WD

Cables are in my hand. If any one has an idea what they are.
First is right under the steering wheel on my right hand side. Plugs into nothing





Second is under the stereo and also plugs into nothing

 

The white one under the A/C control I believe is for the Glass Break sensor microphone.

The black one is for the PDC switch - park distance control, if Im not mistaken.

 

I think they just wire up stuff for options that aren't necessarily there, my 2 wheel drive has a wiring harness going to the back of the coin holder where the four wheel drive knob should be.

 

I totally understand. I just actually need to know what those wires are to understand if I can use them.

 

Thank you!
