Default Wiring an EJ22T ecu into a 1995 Legacy

Does anyone have any pin outs of how to wire this?

It's a royal pain in the arse. It's 95% the same as wiring in a 94-96 JDM WRX swap. The big difference is in the ignition system and the use of wasted spark versus COP. I've done one of them and it sucked ballocks.

You can get the Ej22T ECU info over on Legacy Central. I dunno who has the '95 Legacy stuff. Maybe search the conversions forum for people who have done swaps into 2nd gen leggies.

most of the wiring is the same, however many of the connectors are different.

here is most of what you need. im not sure the NA wiring will be the same as its for a 90-94, and you have a 95. however all the trubo wiring should be what you need...

i made this spreadsheet because i am doing the same thing right now but its on a 93.

I think you misunderstood my statement. When I was talking about the wiring being the same I meant he would be doing the same thing with the Ej22T that he would be doing if he were using an Ej20G harness. In that respect the connectors are not different.

If you are doing it on a '93 Legacy it's a no brainer. It's about half a dozen wires for the boost stuff and that's about it other than switching around cam and crank sensor locations.

But when you jump forward to the '95, as you indicated, the primary connectors for the ECU and to the engine itself are different. Personally, if I were putting an Ej22T into a '95 Legacy I would seriously consider pulling in the complete Ej22T harness into the '95 and alter the wiring for the dash and other things that are different to mate up to the "new" complete Ej22T harness you've already got in the car. We're in the middle of putting an Ej205 into a '97 OB and that's the approach we are taking with that car. But then we think we can make the dash of that car fit, leaving the door connectors and the headlights that need to be rewired.

And please understand that I am not suggesting you don't know what you are doing. You clearly do. I was just concerned that when people read this it sounds like you and I are telling him different things, when in fact we aren't.

I have a conversion harness to plug the ej22t ecu into the 95 connector. It had a problem with drawing power constantly, but otherwise it ran the car fine.
