Thanks

I,ve edited this post to remove the diagrams which are incorrect.

I also have a diagram for a SOHC EJ20 which is also for the 3 plug ECU, it also seems to be right. But I have not got around to comparing it to the above diagrams yet.

Thanks for your replies i will check this out tomorrow i have a manual which is almost right with the color codes but there is no pin outs of the ecu

That pinout is not correct for an EJ22 Aus engine. There is also 2 different pinouts and ecu's that will run the same engine in the Gen 2 Liberty so be careful which you use. 94-96 is different to 96-98.

You could always pay $250 and get the wiring stripped, prepped and labelled for you. Connect B+, Ign switch and Starter signal and it'll run. :)

Yes I get it you make looms, doesn't help us out finding a pinout thought.

crzbug67 try your local libary, I just found some diagrams there. "EFI and Engine Management" (the are 4 volumns) or the Liberty manual.

Merry Christmas. Blame photobucket for them being upside down.

Thanks for that, just had some time to compare it with what I got at the library the other day. Corrects one terminal of I have and fills in all the details that don't get included in the non factory manuals.

Cheers and Merry Christmas

Put this in a more readable format, let me know if you find any errors and I will fix them up.
