The 24 Volt 7-PIN connector N.
Definition
The 7-PIN connector N (24V) is a robust standard for basic lighting on towed vehicles in the 24V class. For example:
- Trucks and semi-trailers
- Agricultural vehicles such as tractors
- Agricultural implements such as manure tanks and bale semi-trailers
- Industrial trailers and flatbed trailers
This connector supplies power to indicator lights, brake lights, rear lights and fog lights. It is standardised in accordance with ISO 1185.
Wiring diagram of the 7-PIN N (24V) plug
| PIN | Function | Colour |
|---|---|---|
| 1 | Left indicator | Yellow |
| 2 | Rear fog light | Blue |
| 3 | Mass for PIN 1 to 7 | White |
| 4 | Right-hand indicator | Green |
| 5 | Right rear lights | Brown |
| 6 | Brake lights | Red |
| 7 | Rear lights left | Black |
ISO 1185 standardisation
The 7-PIN N connector for 24V is specified in ISO 1185. Although the pin configuration is similar to that of ISO 1724 (12V), these connectors are not interchangeable due to differences in voltage and shape.
Applications: truck, agricultural vehicles and more
This connector is widely used in the world of:
- Tractor-semi-trailer combinations
- Trailed agricultural machinery
- Mobile implementations (compressors, generators)
- Exceptional transport

Adapter use and transition to 15-PIN connection
Many modern trailers use a 15-PIN connector (ISO 12098). In such cases, a temporary adapter may be used, but a full conversion is recommended.
LED lighting and CAN-bus interference
On 24V vehicles with a CAN-bus system, LED lighting can cause interference via this connector:
- Flickering or non-functioning lighting
- Fault messages on the dashboard
- Lighting that stays on
Solution: use CAN-bus compatible lighting or a resistor solution.
