speedometer wasn't working on a 96 accord ex automatic, it would work once in a while, but usually not

so we switched out the cluster, got one off ebay, from a 95 accord ex i guess...automatic.

seems like it works fine, except the RPM tach is WAY off. according to that we're shifting at 8,000rpm + at like 2/3 throttle. constantly at way to high of a rpm.

any idea's? bad cluster again? dont know if it matters but it doesn't have a ABS light, and the oem one did....abs doesn't work anyways so its no big deal.
