assuming we talking as if the clocks were to be fitted to a 1.3 ohv engined base spec, the rs rev counter wont work, even with the link to the coil, it will over-read terribly.

from memory havin read up on doing it on mine years ago, its either a massive wiring job, or judgin by a similar thread in the technical room, u need to source the clocks from a 1.3 eclipse model
