My truck doesnt have day time running lights so i don't have to worry about it but my last company truck was an 06 F350 and I just took the fuse out for the drl's and I also did it on our other trucks which were 06 F250's for the guys who didn't want them on. I don't have the manual right now to find the exact fuse but i'll find it for you.
i dont have drls
but you know my 02 had a way to have the fogs n if you pulled em and had the switch in auto
but the 06 does not, so i keep a white cloth with the american flag n it, displayed over my light sensor so we have drls sort of
