'91 ECU wiring diagram wanted

[joshuaj]

Hey all<P>I am looking for a wiring diagram my ECU (91 model), specifically the PRC solenoid wire. I have tried the wiring diagram on the mx-3.com however this does not seem correct as the pin that it indicates is empty on my car. Any help would be appreciated<P>Joshuaj

91?

[joshuaj]

Yes indeed.<BR>Imported from japan. it is the only one here in New Zealand that I have seen with the MX3 badges. All others have Presso. But yes my registration says 1991. <BR>josh

Cheeers for that jeff<P>And here is the latest. I did some hunting in my engine bay and found the PRC system. It seems that it is not controlled by the computer at all but rather the vacuum is supplied by a line running directly from the intake manifold. <P>Guess that rules our my chances of making a semi permanent modification. Oh well. <BR>Back to the drawing board looking for more mods. <P>JoshuaJ
