The ports come with instuctions. You have to take your bumper off, mask off the outline of the port which will be cut out of the bumper. The cuts should be made slightly smaller than the port itself. You can cut the openings out of your bumper with a dremel that has a jugsaw-like fitting. Just be patient and careful.

I don't know if anyone has installed these without a crease. Unless they bought the whole bumper.
