the easiest way to tell if you have the 'old' or not is to look on the right side of the engine, just ahead of the coolant pump. on the head. The '02s had the IAT sensor mounted right there on the intake port runned as Max stated. It's very easy to see. The H-D relocation kit came with a new IAT sensor and you left the old one in the head, just unplugged.... with the wires now running up to the newly installed IAT. If you find that sensor there ('02 models only) you need to leave it there or make provisions to fill the hole in the head where it mounts so there won't be an intake leak.
