I am not aware of that 2012 still paper were used at service shops. At VAG they started around 2010 to document all in expensive SW which need to be online at a central server of VAG. So they have full control on what you see and demand. Also the technical information were reduced to service level. Seems understanding things was no longer in focus, just to get it done was it. Maybe on of the Honda service guys can chime in to clarify this. I found despite that a link: 08-10 Honda Accord SM (mediafire.com) from a reliable source: Honda Accord 2008-2010 Service Manual (Downloadable PDF) | Drive Accord Honda Forums. I didn't download anything. So it is own your own risk....service manual for a ~2012 Accord Euro or TSX with K24Z3?
Great and thanks for confirming the link. I am glad this could a help for others too.thanks - I have that 08-10 manual downloading already. It's the right block; reportedly other wiring changed significantly between 2010 and 2012 but that probably doesn't matter to me as long as the engine harness matches.
They will find it when they search for "Accord Euro service manual"Might be worth keeping the 10-12? link too. It asks for payment so I didn't try it, but someone may still find it valuable.
