Yes, I read it on F150 online, do a search. But I did not do it because it entails takeing out your light switch, and fileing a portion of the plastic stop away so you can pull it out when just your parking lights are on. It really does not sound like too much of a pain, but if you mess it up, your switch will be able to turn around freely with your lights on or off. The post I read had several pictures to walk you through it. I did it on my SVTF, and it is awsome, but that was a easy 1inch wire installed from one fuse to another because the switch already pulls out.
