I will have to convince someone with a lariat to pull out their radio bezel and get me some pictures of where the part number you gave me hooks to the air box... My goal is to have it work like it did stock which I believe was on the upper level setting only.

Yep that is how it should work.... When I was researching I found the bottom of the air box needed replaced, if you look closely you can see the oval where the duct should sit at the air box...or at Least the top half. It appeared that you would have to take dash apart to get air box apart.... And that was too much work for me....
