THe parts circled in red are the important changes between the WM and WN harnesses. Those are the interface connectors in and around the fuse box.

But now i am realizing something. We are just talking about the engine harness but the ECM is not necessarily part of the Engine harness it is either part of the chassis harness or a separate harness by it's self. SO if he is taking that also you may need just about every harness forward of the firewall. Find a part out situation for that.
Thanks Steve!

Hey Steve . I know this post is a few years old and that could be why that link you posted "can't be reached" is there a newer link /p/n ? I need the Pass side engine harness that goes to the right side of the motor and continuing to the transmission for a 2013 L77
I can't seem to find one for the L77 just the LSX
Thanks
Walt
