Designed for Essential Trailer Functions
A 5-pin trailer connector is commonly selected where the trailer requires a relatively simple electrical interface.
Depending on the wiring standard and application, the available circuits may be used for functions such as:
- Direction indicators
- Tail or running lights
- Brake lights
- Earth/ground connection
- An additional required trailer circuit
The exact pin assignment can vary by product specification and regional wiring practice. Buyers should therefore confirm the required wiring diagram before installation.

Reliable Plug-to-Socket Connection
For trailer applications, connector performance depends on more than pin quantity. Mechanical fit, contact quality, cable entry, strain relief and housing construction all affect the reliability of the electrical connection.
Depending on the model, available features can include different housing materials, contact materials, cable entry structures and locking arrangements.
The plug should be selected together with a compatible 5 pin trailer socket and wiring configuration to ensure correct electrical and mechanical matching.
Secure Electrical Connection
The five-pin configuration provides multiple electrical circuits for compatible trailer systems. Pin assignments can be specified according to the wiring requirements of the towing vehicle and trailer.
The connector housing and terminals are designed for stable electrical contact and repeated connection during regular trailer operation.
