Diag Port Connector

Today I tested the microTach on a Softail Deluxe. It worked great. Therefore it is confirmed that the microTach will work on all TwinCam's with the J1850 serial bus. Which are all models 2004 or later. Also, all HD 2004 and later use the DT-04 connector, so if you want to use as a temporary install for diagnotics or tuning. Just add the connector and plug into diag port. There is a link on product page to a vendor.
