Default Ej20x wiring diagrams

I need some help sourcing the Jdm ej20x wiring diagrams. This is for a gc swap and is hard to find because it is dual avcs. Any help is appreciated. Thanks!

You may want to try some of the Aussie forums. That said, I'm looking into doing this in a GC next year as a track specific car and have resigned myself to rebuilding the entire wiring harness in the car. The 16bit ecu cars are just missing too much to fully integrate the dual avcs easily.

That said, it might be worth looking into converting it to single avcs and running it on a 16bit avcs ecu. If you have a DBC donor I don't think it would be too difficult and according to my tuner it's the intake avcs that makes a bigger difference on low end torque.

Keep this updated though so the rest of us can see your progress.

The EJ20X wiring is quite different between pre-facelift and facelift versions.
The facelift comes with TGV's, a secondary air pump and some of the late JDM models have VDC.
And there's the not insignificant issue of different type of sensors, as detailed in this lengthy topic:

You can go directly to this post, maybe it sheds some light:

I didn’t see your post I’m sorry. I definitely have pre facelift. Everything I have tried leads me to going to iwire so I’m probably doing that. I just don’t ah e the dough for the last right now.
