nevermind... I just figured out why I couldn't find that part number... you're in australia and have one of them there foreign Harley speedos in KPH! 67197-99a is the larger Softail/Road King speedo in KPH.
The connector is a 12 position Deutsch DTM (Mini DT series).
you can order a complete one from www.deutschconnector.com
. It would be the 12 position DTM "BLACK KEY POSITION", p/n: DTM06-12SB (comes with stamped sockets that you can crimp with a normal pair of good barrel connector crimpers....
Or, you can order the parts from H-D:
74119-98BK - connector housing 12-way (1)
74152-98 - connector secondary lock 12-way (1)
