For just the conversion without any H13 to 9007 pigtail adapters, choose the vehicle application selection "Ford F250,F350 w/ 05+ lamps 1997-2004"
If you do have H13 to 9007 pigtails, you can either use the same selection above by taking the pigtails out, or select the "Ford F150,F250,F350 2004+" option instead.
