All of these numbers are covered by a DIN standard. A couple of years
back, I think one or two listers tried to order a copy of the standard
from Beuth Verlag (the DIN publishers) and I think at least one web
page was started. For the life of me, I can't remember the URL.
This is a copy I stole earlier:

DIN Standard Terminal Designations
Someone stole this file from a Q lister who was cool enough to put a text
version of it on his web site. Then _I_ stole it from _him_!
The purpose of the terminal designation system for automotive electrical
systems is to enable easy and correct connection of the conductors to the
various devices, particularly in the event of repairs and equipment
replacement. The terminal designations do not identify the conductors,
because devices with different terminal designations can be connected at
the two ends of each conductor. For this reason, the terminal
designations need not be written on the lines which designate conductors.
A list of all terminal designations is given in DIN 72552. In addition,
designations in accordance with DIN-VDE Standards for electrical machines
can also be used. If in the case of multiple-contact connections the
number of terminal designations as per DIN 72552 does not suffice, the
terminals are consecutively numbered using numbers or letters whose
representations of specific functions are not standardized. The terminal
designations in the Table below only serve as examples.
