Please help somebody.....

Have a problem with HONDA INTEGRA 1.8 of 2000 year production.Mehanical
transmission.

I need wiring diagram of engine perfomance.
Engine Control Module 37820-Р73-G01
1117-106035
cwh WH

ECM have four connectors---A B C D. But connector B is not in use.

I think that it is european variant of HONDA. Not ACURA. For American variant of ACURA INTEGRA i have wiring diagram in MITCHELL on DEMAND and ALLDATA
but they are not really for HONDA INTEGRA.
