Lil Bully 66 Posted May 12, 2021 Share Posted May 12, 2021 I just took a 2001 R688S 8LL and put it in my 1989 R688ST. Can someone tell me if i can make the 2001 Speedo function and work in my 1989 ? Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted May 13, 2021 Share Posted May 13, 2021 (edited) The speedo from the '01 needs the V.E.C.U. to operate... I would expect it won't work. ,what does the back of the '89 speedo look like, I havent seen one in a while, so i'm forgetting.. there should be 10 dip switches, its the plug i'm forgetting.
