Is it true that the rev counter wont work if they are put in a petrol car? If so is there anything that can be done to make it work.

They actually bother putting rev counters into diesel cars...  Must be fun watching the counter go all the way to 3000 rpm then back down again...

Yeah a set out of a diesel wont work at all, i had this problem b4. Besides the fact the rev counter only reads up to 6k (petrol ones are 7k) you wont get a reading because it is calibrated differently. And it wont work if you try and swap over the rev counters from a petrol set of clocks either, i tried that but the needle wouldnt read above 4k (found out later on that the PCB on the back is different for diesels too). A set of clocks out of any petrol corsa with the same speedo drive as yours should work fine, but on the 1.2 you will probably have to run a wire from the 9-way square plug from the ecu (green wire) up behind the dash for it to work. Just trace it on the PCB from the back of the rev counter and you should see which contact it needs to go on. i pinched a metal connector from another corsa so i could fit it in the plug properly 
Hopefully been of some help!

Diesels don't have an ignition coil, so the engine speed is read differently and carried in a different signal.
