I think I can help some. I have a PDP-11/45 From U. Wisc. ECE that
claims to be S/N 1525 .
* I do NOT have an actual wire list, it seems, but I will hunt a bit
more tomorrow or Tuesday.
* I DO have earlier PDP-11/45 CPU drawings, but no ECO info
Here is what I have for drawings:

And some diagnostic listings for the 11/40 and 11/45.
I have not looked through my fiche for ECO info, though I am not
hopeful, but will look tomorrow. Most of my fiche are too modern.
Let me know what you want me to scan - should be able to get to it later
this week.
