The rev counter needs a 12v and ground too, you should check it is getting those two, as well as the tach signal. Look at the ribbon connection on the back of the rev counter to check the readings

Hi again, got 4 connections on the rear of revcounter, E _ F G the blank has no wire connected to it, which of these will be the power supply to the unit, sorry to be such a dummy but rather ask than fry the wiring, cheers Mawsy

Pretty sure it’s. Gnd - space -12v - tachometer signal
There is a thread ‘ replacing the dashboard plastic pcb’. Which shows the rear of a tachometer dash. Do a search or keep scrolling down to the next page of threads in this section.
