NSS / backup lights question

I tried tracing the connections for the reverse lights and the wiper switches on both diagrams for 1965 and 1971, since I'm trying to make the two compatible.



I still can't really see where the power feeds in. I've highlighted the wiper stuff in green and the reverse in purple. Am I doing this right?

(Sorry for the size of the pics. I like to be able to read the labels.)
