Head light switch

[1973Camaro468]

I'm trying to figure out what wires hook up to the headlight switch, based on stock colors. Such as:
What do the following wires, originally on the factory headlight plug, supply power to?

Blue
Brown
Green
White
Orange

Thanks for all your help, I hate electrical, so this can be very confusing for me. Tried looking at the diagrams and got lost, lol.

1970 Camaro, non A/C.

Middle of the diagram, towards the bottom, is the light switch wiring
