NSS / backup lights question

i have a service manual for 65.

my problem, i think, is that i don't really understand how the electrical system works, or how to properly interpret the diagrams.

also throw parts in from different years and it leaves me even more confused.

anyway, i'm reading up on some fundamentals.

I do agree that some of the interconnect stuff can be confusing. The Mopar wiper systems through the years are generally very poorly explained.

But if you can post specific questions, we can waltz you through things most of the time.
