What is a Trailer Plug Wiring Diagram Australia and How is it Used?

A Trailer Plug Wiring Diagram Australia is a visual representation that details the function of each pin on a trailer connector and the corresponding wire colours that should be attached to them. These diagrams are essential because different functions, such as brake lights, indicators, tail lights, and reverse lights, are assigned to specific pins.
