from memory,, as I have had same probs,,
there is a black plastic trip panel that has three screws on it,, that you access once the engine lid is open,,,, then, another three screw underneath that (might be four),,,, then it simply lifts out,,, they can be stiff, and the end lights push outwards slightly to let it come out,, watch the paint on the bumper as when you pull them out,, they suddenly let go,,,
lights all just un plug,,,,
when you are taking the sencond set of screws out,, be sure that you are not unscrewing the adjucment screws as the panel has adjusting screws on each side so it can be set level with the bumper/engine lid...
cheers
