hi guys im new to scooby.
I have installed a 1999 ej20 turbo from forester gt into a my 03 forester with the sohc 2.5 na.
I stripped harness from the gt and stirpped down so it has just the engine harness and boost wires etc.
I purchased a j2 ecu jdm from a 1999 wrx sti.
closest ecu pinout i can find for the my03 is a my o3 rs impreza 2.5 sohc with 4 plugs.. not 100% its the same..

just wondering what minimum wires i need to hook upto the ecu to get engine running, im going to keep the old ecu in just to run the extra stuff in the car and bridge in whats needed to run the engine with the jdm unit.

oh and the my 03 is audm aus spec so keeping the origonal ecu still runs the immobiliser.

any help or experiance with the swap will be greatly appriciated..
diagrams would be awsome, oh i did download the service manuals and cant find the ecu pinouts in them.

thankyou in advance!!!
