Hi again guys,
I'm having trouble getting my rev counter to work with the 406 ECU.
I have wire 426 (Pin 43 from the ECU) to the tacho wire on the brown 205 plug.
I have modded the rev counter using this guide:
I have nothing on the rev counter and when I hook up a frequency counter on the tach wire, it measures all over the place and not the 22hz autodata says.
I'm stuck at the moment so any help at all would be really appreciated.
I'm guessing this could be an earth problem as I also don't get an earth on the blue coolant sensor which Autodata says should go straight to negative?
Thanks for you time guys.
