The verbiage on the bottom of the schematic (can't see it in this image) is accurate and addresses your questions exactly.

I ended up wiring the entire circuit using distribution blocks depicted and just Velcro'd them to the back of the firewall (if you have room). I can't recall exactly what positions the headlight switch needs to be in to operate the flash to pass vs. high beam but the RF harness makes it real easy to wire it. There is a plug that connects from the FR harness to the back of the switch.
This is the diagram I used and it all worked great!! I also used distribution blocks and jumper wires.
