anyone have reliable pinout diagrams for obd II 95 & 96 ej22 & ej25? looking for ecu pinouts for all four year/engine combos but at least for a 95 ej22 and a 96 ej25 or if someone can point me in the right direction i'd appreciate that too (please don't bother saying search the forums, though - i did)

 

got the 92 ej22 i put into this guy's 96 outback running beautifully without a cel for the egr as anticipated (96 ej25 had an egr, 92 ej22 has no egr and so the egr solenoid connector is not hooked into anything). i've driven around a bit, got it up to temp and fiddled with other stuff over and over but i'm still waiting for the egr code to show up. should we just smog it as is...?

 

i got a 95 obd II ej22 (no egr) ecu thinking maybe when the egr code came up i could swap in the 95 ecu. well, i tried swapping it in to see what would happen and the 95 ecu won't even run the 92 ej22 through the 96 harness (with all the 96 sensors, etc.). i'm thinking its cuz of differences in the pinouts so i'd like to check there.

there's another thread about 95 TCU's and stuff and how to get rid of the EGR code. it was active in the past few months, that might help. it goes into detail about how the 95 ECU detects manual (no EGR) or automatic (EGR). a user used this info to get rid of the EGR code. i'd look for that thread.

 

i would guess your EGR code is going to show up at some point. after the swaps i've done it usually takes awhile to throw those.

 

the 95 ECU alone won't solve this...it will take some massaging.

this one? http://www.ultimatesubaru.org/forum/showthread.php?t=87100&highlight=ecu+pinout

 

i scanned over it to see if anyone gave a link to pinouts or something but after rereading it i think i should be pursuing an egr equipped manifold - the 95 ecu won't even communicate with a scanner through the 96 vehicle/harness.

or an egr equipped 2.2 manifold?

I can fax you the pinout drawing from the '97 Impreza (EJ22) if you drop me a fax # by PM if you think that would help you.
