Well when I purchased my Pathfinder the foglamps were all cracked and broken. I decided to order some new foglamps off ebay which were like $35 shipped. They came pretty quick and they are very easy to install.
All I had to do was turn my tires and remove the inner fender screws(4 total). After that I was able to pull the inner fender back to access the fog lamp. I just had to remove 3 screws to remove the fog lamp. Just reverse it all from there and you are done. Sorry I did not take pictures from beginning to the end.
