When upgrading to 05-07 headlights exactly WHAT ALL is required to put them in these trucks?
Mine is a '99 XL. If your upgrading from the sealed beam its a little different, for me at least. There is a harness for the 6054 plug for the sealed beams that connects from the 9007 plug. You follow the wires about 6" back and the 9007 will be behind the header panel. Also 2 of the 3 the holes on each side that the lights pop into didn't hold for me. I had to use some hitch pins to hold them tight. That part was probably not common, but I guess can happen. The 9007 plug is something that took me a little bit to figure out because its not visible.
