bump

Diff wiring system will prob be the issue.

Speedos and the associated part numbers usually only fit 3 to 4 model years

ABS/ Non ABS / 6th gear light and wiring changes no doubt

I had a spare stock speedo for a 2000 Deuce , and I sold it to a guy who put it in a 2007 , and it "worked" but no 6th gear indicator light etc etc
