What is this light on my dash?

[zippityDu]

Made a little progress when I started plugging things into the correct areas. Funny how that works.

I have attached the following codes. I’m wondering if the oxygen sensor has anything to do with the lone wire not plugged into anything and lying on the manifold 🤔. I’ve attached a picture for that as well.

ill be researching how to remedy these issues. Any guidance is appreciated.

thanks.
