Default rev counter showing half revs!!!!!!!!!!

just fitted rs2000 1992 ecu and loom.
the rev counter is at half revs, the green wire from the engine loom only makes half revs and i need full revs for the rev counter i have got.
does anyone know where to connect it so i get full revs?
there is no green wire from the edis module like on most ford looms

If your car/tacho was originally for a std type coil, then this can be fixed easy with a tacho driver, about Ł30, this would then give you the correct square wave that the early tacho's need.
