Trailer Plug ORNO 13-pin 12/24V model 4556 for towing electrical connections

ORNO 13-pin 12/24V trailer plug model 4556 is a plastic tow connector designed to provide power and signal transmission between a towing vehicle and a trailer or caravan. The 13-pin layout supports standard lighting circuits, indicators, reversing lights and an auxiliary power line, enabling safe and compliant electrical connections for towing applications.

Advantages

The connector is made from durable plastic that resists corrosion and outdoor exposure, offering reliable electrical contact in wet or dusty conditions. Its 13-pin configuration allows for a wider range of functions compared with 7-pin plugs, including separate circuits for reversing lights and auxiliary power. The compact design simplifies mounting and handling while maintaining separation of contacts to reduce the risk of short circuits.

Suitable for

• Towing light and signal connections for trailers and caravans
• 12V and 24V vehicle electrical systems
• Retrofit or replacement of existing 13-pin trailer connectors
• Applications requiring separate reversing and auxiliary power circuits

Key specifications

• Pin count: 13-pin configuration supporting lighting, indicators, reversing lights and auxiliary circuit
• Voltage compatibility: 12V and 24V systems
• Material: durable plastic housing designed for outdoor use
• Connection type: male trailer plug for vehicle-to-trailer electrical link
• Environmental resistance: designed to withstand exposure to moisture and dust typical of towing environments

How to use

Ensure the vehicle and trailer electrical systems are switched off before making connections. Align the 13-pin plug with the corresponding socket and insert fully until it seats securely. Verify that each function (tail lights, brake lights, indicators, reversing lights, and auxiliary power) operates correctly by testing the lighting and signaling functions with the vehicle and trailer connected. For installation or replacement, follow the vehicle manufacturer’s wiring diagram and secure wiring with appropriate fasteners or cable glands to prevent strain on the contacts.

Usage recommendations

Regularly inspect the plug and mating socket for dirt, corrosion or physical damage and clean contacts with appropriate electrical contact cleaner as needed. Avoid forcing the plug if alignment is incorrect; check pin orientation and socket condition before insertion. Use dielectric grease on contacts to improve corrosion resistance for prolonged outdoor use.
