If youre talkin about 97-03, all i did was pull the DRL fuse out of the box in the glove compartment, but that keeps the corner lights on too which personally looks better i think.
I love driving with only those lights on when the sun starts going down, looks great. Looks like this, but its actually dark in this pic and it looks better mid-day.
i wired these up day after i pulled my DRL fuse. when the sun starts to go down i drive with these on. no HID's in the fogs yet
