I think that might go to the smog pump if you have one.

Looks like you've forgotten to plug it back into the low pressure switch on the side of the A/C drier mounted to the firewall. In your first pic, its the connector pointing up from the bottom left corner of the pic.

I have that one plugged in.I was told it might be a smog pump plug in and my truck didnt come with a pump.

That kind of looks like the plug that goes to the under hood reel light.
