After many week of trying to find an Australian wiring diagram for my 2007 CRF450x, I ended up launching an inquiry process with Honda Australia. After about 3 days, Honda called me directly on my number I provided in the inquiry, and confirmed I was the owner of the motorcycle before sending me through a PDF copy of the Wiring Diagram. I have since used Photoshop to colour this diagram to easily trace wiring, a link to which I've attached below.
The Diagram contains all wiring for horn, indicators, LED tail and brake lights, alternator, flasher relay, and everything that is included in the ADR wiring loom attached to these bikes when they are sold as road legal in Australia.
ENJOY
