I need to see Isuzu 4HL1 engine ECU pinouts - 1989 Mercury Topaz

no car told at all just 4hL1 Diesel floating in Isuzu space?
no year told 2005 (wild guess me)
the ECM gets all power from 2 things the power on relay and a fuse.
the shop manual is by the car or truck and year and model
the VIN number also tells what it is.
why post only and engine????? found it on some huge AC power generator or boat or what?

I say call Izuzu and ask them for the book, there is no other way.
no country told and ECU vary by, you guessed it too, country/;

If it is available for free it is here. The website Scribd has it for cost.
