Im having the same issue with my speedo n stuff too, Have you by any chance done a manual conversion?
Ive replaced everything and it still wont work, cluster piece, speed sender unit, harness in between, manual converted ecu, even had it rigged up to a battery sittin on the passenger seat, still nothing. Aparantly the man speed unit puts out a different pulse than the auto sender and cant be read by the dash or something. Unless you wanna go to a proper place where they will pull your pants down over the price and give you a nice little converter thing as a momento
