mate i got the exact same setup as u.sw20 ecu and 3sgte in my 162. i didnt' do the wiring, but from what i can see i'm only using the sw20 ecu.also they used my standard st162 fuse boxes anf wired into that. if u want i can go out and check specific stuff for u if u want, just let me know..i wouldn't mind learning more about it too.
