My freind has a USDM 98 honda civic hatchback CX (final assembly in Canada), he bought a usdm 99-00 civic si cluster, the clip for the rpm part in the back, clipped right in.... but the rpm wont register??? whats up? the needle SLOWLY floated up to, and is now floating between 4 and 5 grand, the rev of the motor has no affect to where the needle goes, and also when we turn the car off the needle stays between 4 and 5 grand. help me out guys.

secondary problem is the speedometer needle is shakey, during normal operation the speedometer needle seems wobbly or has a shakey effect whenever decelerating or accelerating. anyone has this same problem before or knows how to fix it please give some advice.
