Where this at

I am install my turbo timer and it say Orange wire = to the Revolution signal. What are they talking about? Keep in mind this is a JDM turbo timer.

What turbo timer is it? Do you have a harness? Revolution usually means RPM but i highly doubt a turbo timer needs an rpm signal.

Its a R-spec JDM turbo timer Part # att244. I have spent almost two weeks installing this thing. Biggest pain in the world because its all in Japan writing. I was lucky to find a post in A Skyline Form. Heres what I have on it as far as information.
Here where the wires go to.
Red wire = 12v power source
Green Wire = ignition
Yelow Wire = Acc.
Grey wire = to parking brake
Black wire = goes to a body ground
Purple wire = Only used in Japan
Orange wire = to the Revelution signal (BIG on that)
I am still dong so research to see if I can find a better information on the wiring. Here is the Diagram that I found on the other form.

That is correct, some turbo timers uses the tach signal to determine cool down time.

So where would be the best place to tap that wire in? I would like to tap into the ECU if possible but don't know the pin number.

I bet that's only if you use the "auto" mode.
