Henryj,
A revised diagram is on the way.

hawaii43,
Although the wires on the original diagram are all drawn in black, there is a color code on each wire in the form of a letter or two. The letters stand for the first letter of the color in Italian. For example, V=Verde (green), G=Giallo (yellow), AN=Azul/Nero (blue/black), etc. The letters are quite small and may require the use of a magnifying glass (which is exactly what prompted me to start drawing these diagrams in the first place).

jimcra,
There are three 11501 diagrams to choose from; one each for 1972, 1973 and 1974. Which one do you need?
