Problem with EA Ghia Dash!!!

well this morning i went to get RWC for my EA Fairmont Ghia so i could register it to my name, my hand brake was jammed had that fixed in less then a hour, just had to grease the pot from the calipers and it was perfect no more killin my brakes while drivin. Now the only problem is my digi dash works fine but its just the speedo that seems to be dead no activity at all, i've checked all wiring which was a pain in the butt, and that little block thingy thats attached to the gear box forgetten whats it called changed it too but still not workin. Im really clueless atm any you guys know what the problem is, i urgently need help and no im not gonna buy a new cluster bcoz the car is due at VIC Roads tomorrow morning 8:30am

have any idea what it could be

Cheers
