When do the fog lights come on?

[JesusArTorres]

My 03 Yukon doesn't have fog lights. If I did, when would they come on? I crawled under the truck today to check other things and noticed this:





Is this where the fogs would plug in? I do eventually plan on getting some.

This is my light switch btw:



Also, I saw this. Anyone know what it is/for? It was already unplugged.

Plug for fog lights

Under headlight dial to the left is fog light on/off button
Also, I saw this. Anyone know what it is/for? It was already unplugged.

I believe that is one of the airbag impact sensors

That plug with the orange is the fog light wire.

And the round button under your rear wiper switch is the fog lights button.

Not sure on that last piece??

Remove a headlight and plug it in to see if it works once you push the fog lights button in. I'm not sure if there is a fog light specific fuse, anyone else know if there is?

The bottom one is your airbag sensor!!! And yes those are the fog light harness's and the button.
