I own a 2003 2XWD 5.4L V8 Lariat and this product fit perfectly.Installation:First remove both the positive and negative terminals on the battery. You can probably get away with just the negative but it is always best to be extra careful. Wait about 15-20 mins before starting work.Next you will have to remove the air bag holder. This sounds way worse than what it is but it is necessarily. There are two caps in the back on both sides of the steering wheel. Use a flat tip screw driver to pop them off. Once off slowly loosen the bolts holding the air bag. Once off the holder will loosen and you can now get to the switches and wire connecting both. Cut five ties holding the wires in place. Pull out and disconnect the old switches and plug in the new ones. I used new ties to make sure the wires did not bunch up. Put back the holders , screws, and caps and you're ready to go.Lastly Test the cruise control on the road and it should work. Mine worked just fine with no issues.*Note: The screws in the cap should not be over tighten. If you do your horn will go off as soon as you plug in the battery. Get the bolts on loose attach the battery and tighten until you hear the horn honk then loosen.
