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?
By "manual", I hope you mean the Factory service manual, not the Owner's manual.
The FSM will have all the wiring diagrams as well as everything else you need to know about servicing your car.

Edit: Boy, I type slow... got treed by 2 guys!
