2 major drawbacks w/this harness. First, why is the fifth wire only five feet long? If you have reverse lights on your trailer you need to splice in enough wire to reach the back of the trailer. Second, what would it take to make this pigtail connector with a cover on it for when it is not in use? A rubber grommet/cover would prevent the connections from corrosion when not in use. Fix these two things and you would have a great harness.
