Hello, just received my replacement speedo/tach combo for 2004 Road King. Went through the instructions including hook up to data link cable, but the OEM speedo was dead (that's why I needed a replacement). Now I can't calibrate the new equipment as the odometer info is on the original speedo. New equipment reads NO CAL the NO SPD when hooked to data link.

Any help on how to get this installed will help.

 

Are you sure that you are getting voltage to the instrument? Both old and new don't work.
