I own a 2015 ecoDiesel Longhorn

Hi folks! I know just enough about my vehicle to be dangerous. I was changing out my air filter and noticed a red switch that was disconnected on the passenger side under the hood directly under the windshield. Since I have been having issues with my passenger mirror retracting I thought maybe it had come unplugged and plugged that red switch back together. Apparently that didn't fix the mirror. Now I am concerned I may have plugged something in that shouldn't be plugged in. Does someone know what the red switch is? I have a photo here.

Moving this for you so hopefully you can get some feedback !

Could be the harness plug for the engine illumination light under the hood. Mine a 2018 didn't come with one. Ordered on Amazon and that's where I plugged it in.
