No pics but if I recall it runs along the driver side rocker under a metal flap or cover. Then runs into the trunk area right along where the inner wheelhouse meets the floor. I believe there are little tabs spot welded there that bend around and retain the harness in place.
Do you have one of the factory service manuals on disk? They usually have illustrations showing all that stuff. Or try here:
