Engine wiring diagram or ECM pinout for a Volvo 8.1GXi (H)

[A1957]

I’m trying to get an engine wiring diagram for a 2006 Volvo 8.1 GXi. The model number is 3869370.
Its installed in a 2007 Chris Craft and I have the wiring diagram for the boat but it just stops at the engine connection.
BTW, if it helps, the ECM is a part number 3885461 and the engine wire harness is a part number 3884250.
I have a number of gremlins I’m chasing (tach not working, intermittent key issues, etc) and this would be a big help.
does anyone have one a pdf they can share?
Thanks,
Dennis

if you want a printed copy of the manual

https://www.volvopenta.com/marineleisure/en-en/for-owners/your-engine/manuals---handbooks.html

if you want to simply look at the manual, www.boatinfo.no

I’ve seen both those sites. Neither are user friendly. I would prefer not to buy the manual and the boatinfo.no site only has a few very old Volvo manuals.
i was hoping I could just find the engine schematic and pinout for the ECM.
