If I recall correctly the top picture is of a harness holder which keeps the MAF connector anchored to the Airbox. You can fashion a zip tie to hold it or just install it as is.

Looking at picture 3 - I see the MAF attached to the airbox, but the connector is installed so it is not the MAF plug.

Is this the 2.5T engine?

Fuel pressure sensor connector but the fuel rail does not have the provision for a FPS. That fuel rail has the fuel pressure test port where the open end should be for insertion/attachment of FPS. Is your check light on? There should be a STC for open sircuit to the fuel pressure sensor, probably two DTCs as the temperature of fuel signal is also missing. The retainer clip on the harness lead would have been popped into the black plastic cover that is not present in the pictures.

That makes sense. Is there a good place where I can see a picture of what you are talking about?
Thanks!
