I have a 62' wagon, bought all new under hood wiring for a v8 hei from classic industries, the head light are a no brainier and some others I know, but so many other wires!!
Didn't come with schematics? If not, would contact either Classic Industries or manufacturer. As much as we all like to help each other its basically impossible for any of us to help without visuals, its a hands on job really.
I'd say most of those connect to your horn relay, which is often also a junction point. Do you have a service manual for your car? There should be a wiring diagram in the service manual. Trying to do electrical without a wiring diagram is like flying blind.
