Purpose of the square hole in belly pan


Must be a slow day ;), but I was under my GT and noticed (again) the square hole on the right forward side of the more forward of the two removable rear belly pans. With a flashlight it appears as though one can look up and see the bottom of the power steering pump, but I'm not sure. Does anyone know its purpose?

It gives a good visual of the oil pump too.

That sure was convenient to have when I was monitoring an oil pump leak and seal replacement.
