New generator field coils

[LizardsA]

Greetings all,
Forgive me if this has been asked before, but I couldn't find any answers by searching through the forums.
I am rebuilding a 1930 generator but "The Model A Generator Book" that I have been referring to doesn't show very clearly where the two wires from the field coils go. There is one wire without a lug on it - where does that go? Then the second wire with a lug on it, where does that go?

I have included some pictures that might help.
As always, your learned advice is most welcome!
