Understanding Your Narva 7 Pin Flat Trailer Plug Wiring Diagram
The Narva 7 Pin Flat Trailer Plug Wiring Diagram is a standardized system designed to connect the electrical components of a trailer to the towing vehicle. This plug, with its distinct flat profile and seven pins, is a common sight in Australia and New Zealand. It facilitates the transmission of power for essential functions such as brake lights, indicators, tail lights, and often, a reverse light. The simplicity of its flat design makes it easy to connect and disconnect, contributing to its widespread adoption.
Each pin on the Narva 7 Pin Flat Trailer Plug is assigned a specific function, ensuring that each signal from the vehicle reaches the correct light or accessory on the trailer. This standardization is vital for road safety. Here’s a breakdown of the typical pin assignments:
- Pin 1: Left Hand Turn Signal
- Pin 2: Rear Fog Lamp (often used for reverse light in some applications)
- Pin 3: Earth/Ground
- Pin 4: Right Hand Turn Signal
- Pin 5: Tail/Running Lights
- Pin 6: Stop/Brake Lights
- Pin 7: Reverse Light (if not used for fog lamp)
The importance of correctly wiring this plug cannot be overstated, as incorrect connections can lead to malfunctioning lights, potential legal issues, and significant safety hazards on the road. For example, if your brake lights are wired to your indicator circuit, other road users will not be aware when you are braking, increasing the risk of an accident.
When consulting a Narva 7 Pin Flat Trailer Plug Wiring Diagram, you will see colour-coded wires corresponding to these pin functions. While these colours can vary slightly between manufacturers, the pin positions themselves remain consistent for a 7 Pin Flat plug. A typical wiring scenario might look like this:
| Pin Number | Function | Typical Wire Colour |
|---|---|---|
| 1 | Left Turn | Yellow |
| 2 | Reverse/Fog | Blue |
| 3 | Earth | White |
| 4 | Right Turn | Green |
| 5 | Tail Lights | Brown |
| 6 | Brake Lights | Red |
| 7 | Reverse (if not used for fog) | Black |
Always refer to the specific diagram provided with your trailer or plug for the most accurate information. Some trailers may have additional functions like auxiliary power, which would utilize one of the pins, making the diagram indispensable.
