Fog light pre wire

I am a new 2023 SR5 owner. My truck has OEM fog lights installed. It did not come with rear bed lights so I bought the Toyota Deck switch and aftermarket lights. When I pulled the lower switch panel out to install the deck switch I noticed another plug in a 'non used' holder socket. So I'am thinking what can I use this for. It has four wires; blue, green, red, and pink. From searches I have done so far it looks like this is for fog lights. But my truck has fog lights and they are controlled by the left knob off the steering wheel. So my questions are, what can this plug be wired for, auxiliary fog/lights? If so where is the point of termnation that the lights can be hooked up? Please let me know what I am missing here. Thanks

 

I highly doubt it's for fog lights because they are controlled from the stalk. I don't have any good idea on what those wires actually do... I am an SR owner, so I don't have all the bells and whistles.

 

Thanks for getting back.

I will pull the switch plate back off and remove the plug out of the blank socket to get a better picture, maybe someone will have an idea from that. It wasn't readily apparent how to get it out so I stopped messing with it last time.
