In reverse order, I think that the 11/40 was the last MP to include an
integrated Wire List. In later cases they apparently were separate
documents. Or those portions simply didn't get scanned and archived to
Bitsavers (or elsewhere) ... they're not in MP0KB11-C0_1170engDrw_Nov75.pdf
anyway.
Yes, the 11/70 has one big, bad, backplane. I think that you're probably
correct that there's a single Wire List for the whole thing -- perhaps just
identified as KB11-C. But I don't know that to be true ... yet :->.

Wire Lists for any/all of the following:
KB11-C 11/70 Processor (or the older KB11-B)
FP11-C 11/70 Floating-point processor (or the older FP11-B, also
used
in 11/45 and 11/50)
RH70 MASSBUS controller
I don't know for sure about the 11/70 (I never looked at one closely), but
for the 11/45 FPP, IIRC that was part of an integral multi-unit backplane
assembly with the CPU, i.e. it was wired as part of a large wire mat that
included the wiring for the CPU. So I don't think there's a separate wire
list for the FPP. I would guess the same is true of the RH70.
DEC generally included the wire lists in the engineering drawings; do the
11/70 prints not include the wire list?
