Need some electrical help with my ‘68 Plymouth Valiant 100

Thank you I will for sure check these out. So another thing, I have ordered an original ‘68 valiant manual, but it won’t be here for probably about a week or so. I’m assuming it will have a diagram showing all of the electrical? Is there a diagram online that I could check out now so I can try to get a head start?
My Mopar has a digital 68 manual for download. There are wiring diagrams in there, it's just black and white so you have to check the legend to follow

There are laminated, color wiring diagrams that you can also buy, that'll help translate. I did colored pencils to colorize my hard copy TSM
