R33 ECU Diagram needed

[blx]

I am trying to install a shift light into my R33 and need to fing the wire that activates the tacho.

I have been told that I need wire number 7 but i have no idea which wire this is. If anyone can help or tell me what colour it is i would greatly appreciated.

cheers

Give this a try.

Be careful with the tacho output. It's very sensitive and has a very high impedence output.

I popped my last ECU by trying to hook up a shift light

Thanks for this info guys!

I went to install it and 'pin 7' does not have a wire running from it so i stuck a wire running to the shift light and hooked up the red and black wires but when i got to the rpm it was suppose to light up it didn't do anything.

Does anyone know what coloured wire comes from the the back of the tacho?

thanks again for the help.

It'll be there, just make sure your looking at the ECU and diagram the right way

Your tacho hooks straight upto pin 7 (and your ABS looks at it as well). If your tacho is working, then it'll be there.. :uh-huh:

I could be wrong here (shocking memory) but I think the tacho wire (pin 7) is brown with a yellow stripe???

Thank you to every one that helped me out!

I fitted it and it works great.

The wire was exactly were you said it was jay i was looking at it upside down... But when i look at the diagram it still looks like it should be the other way round...

For anyone out there reading this about to do there own my R33 GTS-t had a yellow wire with a blue strip through it as the tacho wire!!

Thanks again for everyone's help will post a pic soon.

THANK YOU !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! i have been looking at google all day for wireing diagrams and all the links to the pages with the pin digrams and wire colurs were bad links this solves that gauges issues hope fully ill test it tonight

lol the funny thing was i tried here first didnt find it thou dose any one know wich wire the stochie (lean/ rich) meter goes to i have a Mechanic mate who wired it up but it dosent seem to display corretly usually i would trust his judgement but he wired up the same gauge in a gtir pulser and it dosent seem correct either

he wired it to the o2 senser in the engine bay i think i wasnt paying attention should it be wired to that or the computer? i dont know enough about the gauge

it seems incorrect because at idle when cold its stochie at idle when its warm its leen but as soon as u touch the gas pedle it super rich and is constantly theres no middle its either lean or super rich it dosent matter how slow u take off either
