hello everyone. I have a 1991 civic sedan that we just dropped a D16A6 bottom end in with a y8 head. Using a td41u dizzy shell with a td42u internals. Running a p28 ecu. My problem is error code 4 which I just can’t seem to fix no matter what wire config I copy on internet. Can someone point me in the right direction here.

Thanks in advance!
