some what funny.. i had the same problem every one says change the speedo sensor. get your hands on a b14 sentra instrument panel. this speedometer is eletric and fits exactly into place of ypur old cable type one. run four wires coming out the back of it and hook it up only problem is it only goes to 180. but other than that u could change the wallpaper to match back your original instrument panel i did this conversion on a c33 instrument panel works fine.
