ok a buddy of mine just recently got a si cluster with the tach out of a i would believe it was a 92 - 95 (not sure on the year exactly that car was destroyed) well anyways we plugged it in into his 95 cx. the lights work on the cluster, the tach and fuel guages all work.. but the speedo does not.. he said at one point it started to jump a little, but i didnt see it do this when he took me for a ride, it just sat at 0.. even the damn shift light works, but it flashes "CRUISE CONTROL" which is funny but ya no speedo.. i checked the connections on the back and the wires.. any suggestions on what to do?? thanks

 

check the wires in the cluster were the plugs connect into the cluster and take some very light sand paper and sand it down very little till u can see the copper in the connector and see if that helps it helped me out
