Yes, that last input was correct, be careful not to break the plactic snap that holds the lower part of the light in place. Standing in front of the truck, facing the light, the plastic snap, is on the right side of the light, just off center, it should sort of pop out, but the object is to not break it off. Prior to replacing it, I put some grease on the plastic coupler, made for easy removal next time. YOU should not take off the grill and lights, that would be alot of work, and really get you no where. Suggestion, any of the auto parts stores sell the small books, most have pictures on this type stuff, and the books cost approx. $15.00. Good Luck.
