Plug/harness ID?

[mois93da]

Guys this plug was dangling off my truck after having to drive in the flood. No lights came on the dash, and driving wasn't really affected. I just can't seem to find where it goes connected. Does anyone know what it goes to? I really hope it goes to an option I don't have

Where is plug located? Is your truck flex fuel equipped? If not could be for the e85 sensor. Whatever it is appears to be unused on your truck, since it has what appears plug in the connector.

Check this post out. Plug looks the same as yours. It's for the e85 sensor.

Yeah I kept trying to peek inside the black plug to see if anything was torn but everything inside seems to be clean. The wires are white, black, and purple/blue. The truck is not equipped for E85.
