4agze wagon

Hey i have a 1990 ae92 corolla wagon that I'm putting a 4agze into. I am using a 1988 fx-gt dash cluster because it has a rev counter, but I'm having trouble fitting it as some of the plugs are different, and i havent been able to find any wireing diagrams. can any bodie help, if i can find a 1988 fx-gt dash wiring diagram and a 1990 corolla wagon dash wiring diagram i can then change the plugs around to suit Cheers Josh
