HELP! Speedometer/odometer not working!!!
 

*NOTE* - I did a search and nothing on this topic

I just finished installing a GSR cluster into my Si and the only problem I have now is that the speedometer/odometer gauge is not functioning. Actually, the speedometer itself seems to work, but jsut not correctly. The needle will not move at all until I reach an actual running speed of 40 mph (60 kmh), and at that point the needle will start moving like normal, just VERY OFF. Basically, it'll show 20 mph when im really driving 40mph.....40 mph when i'm on the freeway actually cruising at 60 mph. What could be the problem??? Also, the odometer is not rolling AND even the trip meter is not rolling. Any help would be appreciated, thanks!
