Question 08 wrx ej20x/y swap dual avcs

I have a 08 wrx that I swapped a jdm ej20y. I have driven around with the exhaust avcs not bein used for 15000 miles but as ive started raising the boost i get compressor surge from 3-4k rpm and even when i lower the target boost and wgdc i continue to get Compressor surge. I read somewhere that Avcs should help with the compressor surge so I bought a 05 legacy gt ecu and wired in the sensors. Where could I find instructions or ecu pin diagrams for connectors 134-137(ABCD) for both 08 wrx and 05 lgt? Also where can I find can BUS patch, immobilizer patch etc.? Thank you!
