Well, this is my second attempt.
First guide was only theorical.
This time, it has been done and tested on my car.
So to quickly sum up (yet another time):
My car had no rev counter when I bought it
My car was not plug and play displaying revs even with SR clocks featuring rev counter (but everything else was working on the clocks)
My car had different wires color code than in the excellent Porkpie' guide:
www.micra.org.uk/threads/40661-K11-Pre-Facelift-Rev-Counter-Wiring-Procedures
My first idea was to piggyback the wire on the black connector behind the clocks:
because according to this picture:
lowest blue line number "2" (and so the wire on the black connector at this place) is standing for the rev counter fuction.
Also; on the ECU side; according to Frank diagram the tacho is pin number2 of the ECU:
The diagram is the ECU male pins when you look in front of the ECU:
or when you look at the rear of the female blue plug connector:
Today, I made another (bad) discovery, that I didn't had any wire on the black connector nor any metal pins:
So I can't piggyback the wire since there is NO wire and no metal pin to make contact...
So I thought I would direcly wire on the soft green plastic sheet, where there is a bit of metal on the track leading to tacho pin:
Piggyback pin number 2 on the ECU (the connected wire was blue but there is many different wires color coding):
You can now see the rev of your engine :
