I just purchased an 03 Excursion 4X4 and was wondering what flashes I might have had or have not? How do I know if I am missing a flash? I am new to the diesel world and have heard good and bad things about the flashes. It seems some people dont let the dealer get close to the truck and some of the flashes seem important. Any help understanding this subject would be great!
