After the debug and the "in circuit" test, I drawn the schematic using Eagle (Eagle 5.5.0), here you can see it:
the above is the version with 9 displays in order to monitor:
- Gear (it's the display in the middle and it's a bigger model)
- Engine RPM or Speed
- Oil Temperature or Weeling Percentage (how much the rear weel is spinning in percentage)
Using the freeware Eagle version, is not possible to route a so big display, so I have reduced to 7 Displays and reoute as follows:

here the top Layer:
