Have Fun!

good info. its missing a couple pins but still great

[decke48]

ill put it in the threads of note

[anothernord]

Great info!

[T_F_E]

so does this mean you can partially see what your check engine light means with a test light?

[itsmidge]

anyone know if the jdm ej25 wires match up to these color wise, i know there are fewer wires on the jdm version but none the less do the colors match up?

[httrdd]

This is pretty accurate correct? I cannot find a pinout and I came across this. It should be the same for my 99 ecu. Thanks in advance!

I wired in my Perfect Power 6 with this and it worked fine.

[httrdd]

Nice info here too!

I also used this to wire in my Emanage Ultimate. No incorrect wires that I found.

Hi all,
Thank you for this useful topic, but it doesn't fit to my ECU, coming from a '98 Legacy outback, EJ25 engine.

Here is the picture of the connector :

JECS 9V
A56-000 R22 7401
Does anybody knows the pinout of this ECU?

Thank you

Benoit (from France)

[Benoit]

Nobody can help me for this particular one?

[anothernord]

You'll probably want to find a JDM or EDM diagram; this is only for the USDM pinouts. I suppose you have different emission setups and stuff.

The pinout stuff here matches the same for the '97 Outback ECU?
