RPM signal wire 3S.GTE

[vinno]

hey guys, i'm trying to help my mate work out what/which is the "RPM Signal wire" to the ECU for a 1990 3S.GTE (JDM) for the purpose of connecting the "tacho" function of a Turbosmart E boost 2.

Any help would be awsome

Cheers Vinno.

You may find what you need here: http://www.alltrac.net/reference/
Alternatively I am pretty sure you can make use of the diagnostic plug to pull a tacho signal from.

[-==L=a=N=c=E==-]

IGF wire from the ignitor.

Or

In the diagnostic port there is a tacho outpu in there.
