2018 Sierra Denali - Anybody know what this wire is?

Anybody know what this? Right under the middle of my truck underneath.

 

Thanks!

I think it may be the plug for E85 if your truck isn’t equipped with it already.

Yep. E-85 sensor connector. Has a dummy cap on it.

Hey thanks, that stupid thing just fell down last week and I reattached it back up with a tie wrap.  Couldn't see where it went, just a connector plug stuffed into it.  My truck is a 2016 Sierra SLE 4x4.
