Decoding the 5 Pin Trailer Wiring Diagram Australia
A 5 Pin Trailer Wiring Diagram Australia is the standard configuration for smaller, unbraked trailers and those with basic lighting requirements. It's designed to provide the fundamental functions needed for road legality and safety. This simple yet effective system uses a plug and socket arrangement, typically found on the rear of the towing vehicle, to transmit electrical signals to the trailer's lights. The colours and pin assignments are crucial, as they dictate which function each wire controls. Ensuring these connections are correct is vital for your safety and the safety of other road users.
The five pins in this diagram are generally assigned to the following functions:
- Indicator Left
- Indicator Right
- Tail Lights (Running Lights)
- Brake Lights
- Earth (Ground)

|---|---|---|
| 1 | Indicator Left | Yellow |
| 2 | Indicator Right | Green |
| 3 | Tail Lights | Brown |
