No, theres no sender, which is why the digi dash doesn't show revs in the revs bit.
You just need to find a 'pulse' and use an electronic rev-counter, tis the easiest option.

Or, just mtfu and use ear/speed. 1st is just under 30, 2nd under 50, 3rd under 70, 4th about 100ish, it runs out of puff, and 5th is a m-way cruising gear, if its a 1.3, which, if it is, it won't be a zetec. It'll either be a 1.3 endura, or a 1.25 zetec...
