I searched but found nothing I have a 90 hatch with a built turbo motor I am trying to wire in my v-afc but I can not read japanesse and thats all it came with can some on tell me how to wire this to a chipped pr4 ecu?

 

If it is a fields try this address. http://prelude.vtec.net/gen5/p....html.....
I got all the info I needed there for my Rex, but it was a long time ago. If the info is no longer there, let me know I may still have the sheets.

 

Sorry, I've been real busy.
This is a wiring diagram for the ECU Pr3
A is the 18pin white plug
B is the 20pin black plug
C is the 16pin black plug

tap 12volt sorce (a25)
tap ICM ignition control module for RPM (a21)
feed vtec solenoid valve through svfc vtec (a4)
feed vehicle speed sensor through svfc vtec (b10)
cut vtec pressure switch to ECM svfc vtec supplies this to ECM

I know it's a little confusing.

here are some other good links

here is some more wiring info I found
from the vafc (green wire tap rpm signal to ecu)
from the vafc red wire tap ignition source
from the vafc light blue connect to speed sensor
from the vafc blue connect vtec signal
the vtm line on the ecu is cut and taped off

Hope this helped a little.
