This Speedo is for the early model 500 and 700 UTVs that have the 2 Circle style display has been out of production for many year. Better news, this newer Style works even better ! Same size and Bolt Pattern.
Some of the 2008-2010 Models only had 4 5 Plug Ends. When Turn Signals were added the 6th Plug (3-wire Triangle) was added. If you have a 4-5 Plug Speedo Display, simply don’t need to use more.
