Unless that is plug, program and play, I would STRONGLY urge you to only use a BMW harness and module.

You could be jerked around by BMW over warranty issues in the future- even if there is nothing wrong with this module per se...just the fact that it isn't BMW gives them something to blame.

Nothing wrong with non-BMW hitches, but the wiring is something else. With the BMW module they also do some programming.
