Does anyone have a ECU wiring diagram of the subaru Legasy engine EJ20NA?

I need only an inside photo about what goes were of the ECU.

I need it for my electrician.

Your help is much appreciated!

Try on Gazman's pages
http://www.osp.metrohosting.info/wiringgallery.html

It would help if you told us what year & if yours is American, European or Jap specification?

Or take a pic of your ECU plugs and I'll try to match them to a pinout diagram for ya. 😀

Well..it is a Japanese SOHC engine,year 2001 and it came out from a Legasy.

I will try to take a picture of it and uploaded here.

Hey Gasman,

Do you think this picture will help you to match for me a pinout diagram??

The electrician tells me that it has an OBD 14pin slot.

hey Jim,
a shot of the ecu unplugged showing the pinout slot would be better. The link for the 98-03 manual is down on my site atm, but there's one here:
http://www.overl0ad.com/LegacyFiles/
Its a big file (69mb) but its the full workshop manual so is worth downloading. it also shows models with and without OBD. Hope this helps.

P.S. gasman? do I smell? lol

Do your ecu plugs look like this-

If they do download that manual.

Hey Gasman..the pdf file does not working.
Are you sure it's ok?

Rgrds,

Did you click on the one named 'Gen III - 1998 - 2003.zip' ? Its a zip file not a pdf and I downloaded it on a dialup modem no prob so it should work for you ok. 👍

Bugaru03 ·

Yes i click on Gen III - 1998 - 2003.zip,then i download the file and then when i extract it and try to open the pdf it does not open.🤖

I'really confused with this because i try to find diagnostic machine with 14pinout in order to read the problem.

Gasman...This is the layout of ECU connector terminals.

Does this looks familiar to you?

Sorry bout the delayed reply,
Check this one:

Its the only one I have with that plug type. It's for a turbo model though so I'm not sure if you can use it.
Maybe compare it with your engine harness?

gazman ·

wait, I found a better one here - http://www.veloce.pwp.blueyonder.co.uk/TT%20PDFs/wiring.pdf
Are you sure its a JDM? It matches the above manual which is UK or EUDM. ❗

Hey Gazman, that looks (SOHC dia) like it matches my UK spec 97-98 wiring. I'll double check later

I couldn't find a diagram for mine for love nor money and buzzed out the whole loom & drew my own dia. GRRRRRRRRRRR

Jim, I wasn't ignoring you. I thought your connectors looked the same as mine. Then you mentioned you had a 14 pin ODB port - mine's 9 pin
