and cheers Lauren but already tried all that as used to have this setup in my mk4 using efi clocks but as its a mk3 now the dials have gone :-(
Laren is correct. Run a wire from pin 11 of the EDIS to the green rev counter wire, this will give you a clean tacho output that you can use with your S1 dials. The EFi dials take the output of one coil drives (usually pin 10). You do not need new dials!
FYI, pin 11 is missing from the usual Ford EDIS harness.
