Thanks in advance. I opened up the hood and found this wire and plug not connected to anything. 2004 F150 5.4. The wire comes from somewhere in the middle of the back. The Wire is shaped/formed not formed.Not sure how it came loose. I can not find a spot to plug it back into. Any help would be welcomed.

That is the vacuum feed to the 4wd IWE solenoid. It's not needed on 2wd trucks.

 

Thanks I looked all over for a place for that.
