what are those wires for?

so i installed sum interior parts on my truck and i noticed that my truck has sum "extra" wiring in the driver side which isnt connected to anything. the two wires that you see on the 1st pic were connected to blank buttons under the AC vent on the drivers side. Since they were connected to blanks i have no clue what those wires could be for. The one in the 2nd pic was not plugged into anything and is just hanging under the steering wheel. any idea what these could be used for? any help would be greatly appreciated.

Toyota prewires different connectors for different things. Under the A/C vents could be for fog lights and mirror controls. The grey connector I think is for steering wheel controls. I could be wrong on that though.

 

^^^this, the gray connector I don't remember what exactly it's for at the moment
