NOTE: Some of the early 2001-2003 models have been equipped with the Delphi® electronic control modules (ECMs) that will work with our adapters. You can find out if your motorcycle is compatible by checking the number of wired pins in the diagnostic port, also known as the data link connector (DLC). If only three of the pins are wired, then it's the Delphi® ECM and the adapter is compatible. If all four pins are wired, then our adapter is not compatible with this motorcycle.
