Just FYI -- as far as I understand, there are three different versions of the nosecone. One with no parking sensors, one with "short" parking sensors, and one with "long" sensors. The long and short sensors have different harness connectors, too.
Since your car is a 2015, it has parking sensors.. but I couldn't tell you which kind. You definitely do not want a 2012/2013 nosecone with no sensors.
