The pilot reported that during the approach and landing, the nose of the airplane "was very heavy", and he was unable to keep the nose landing gear from striking the runway. An inspection of the airplane revealed that the elevator (pitch) trim control was reversed. The 2007 model airplane had a provision for the installation of an aftermarket electric trim option. This meant that the airplane was delivered to the customer without an operating electric trim system in order that the airplane could be retrofitted at a later date. Prior to its departure from the previous airport, the airplane's manual electric trim was enabled in accordance with the appropriate manufactures service bulletin. A subsequent inspection by the airplane manufacturer revealed that the wires connecting the yoke's trim control switch were incorrectly labeled. Therefore, incorporating the trim system service bulletin would reverse the direction of the pitch trim control from the pilot's input.
