headlights are 9007, fogs for the HD are H1 or H10 (I forget which it's been so long). Basically if factory is H1, you need H10 HIDs and you remove the jumper harness pigtail. If I have that flipped, and if factory is H10, you need H1 HIDs and you remove the jumper harness pigtail.
*edit* wow this has been so long since I thought about this stuff, there was a thing about roush fogs years ago. Maybe that allowed the OEM style bulb to fit, or maybe it was something with the mounting that H1 or H10 fit directly into the roush fogs, but OEM fogs it took some modification? My HD archives are getting dusty lol. NHTOC is probably a better site to search up info on that.
