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:
B-DD-11/45-0-AJ Basic Assy (PDP11/45) 5/72 [Not CPU Cards]
D-CS-5409684-0-1-H 11/45 Console Board 3/72

M8104, M8105, M8106, M8109, M8116, M930, M9202]
NO wire list
(Curiously, I also have KB11-C, 11/70 drawings.)
B-DD-MF11-U-B 16K Core [M8293, G235, G114, H217, M7259 (Parity Control)]
B-DD-MS11-B-B MOS Memory [M8110, G401]

EK-MS11A-MM-006 MS11-A,B,C memory System Maintenance Manual
PDP-11 Systems Course Training Drawings
PDP-11/45, 11/70 Maintenance Course handout book
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.
