MANTES electrical installation, boat trailer harness 9.57m, 13PIN plug, 2x 5 PIN bayonets
The MANTES electrical system is a complete and well-thought-out wiring harness designed specifically for boat trailers . This "board kit" is designed for trailers equipped with a removable rear lighting beam , a standard solution for boat transport. The removable beam makes it easy to launch the boat without risking damage to the lights or wiring. The kit allows for safe, tight, and easy connection of the entire lighting system – both the main rear lights and marker lights – while maintaining full functionality and resistance to water and adverse weather conditions.
The first part is the main harness with a 13-pin plug , 7.8 meters long, along with a 2-meter marker light cable – for connecting the electrical system from the towing vehicle to the trailer's rear beam. The kit also includes a 13-pin plug socket for self- assembly on the beam , allowing for quick connection and disconnection of the entire lighting beam.
The second part includes a connector for the rear light bar (e.g., removed for launching a boat). The 1.77-meter cable is terminated with 5-pin bayonet connectors for connecting the rear lights. With a high IP67 sealing rating, it provides excellent protection against water, mud, and dust—ideal for use in wet conditions, such as boat transport or off-road use. Additionally, the cable features an integrated branch for two 0.35-meter wires for the marker lights, which effectively mark the vehicle's dimensions both day and night, improving safety during maneuvers and driving in challenging conditions.
The set is complemented by an additional 15-meter cable for convenient connection of marker lamps located along the entire length of the trailer.
Supported lighting features







The beam supports lighting functions: left/right position light , which ensures the vehicle is visible when driving at night; left/right turn signal , which allows you to indicate your intention to turn; brake light , which signals braking; reversing light , which facilitates reverse manoeuvres by improving visibility behind the vehicle ; fog light , which increases safety in difficult weather conditions, such as fog or heavy precipitation; left/right marker light , which highlights the outer contours of the vehicle, improving its visibility on the road, especially at night and in low light conditions; and license plate light , which ensures the visibility of the vehicle's registration number at night .
Trailer wiring harnesses are essential for ensuring the proper operation of lighting in car trailers, trailers, agricultural trailers, and caravans. Their primary function is to transmit electrical signals to the position lights, brake lights, turn signals, and fog lights, significantly improving visibility and road safety . Using high-quality wiring harnesses helps avoid problems with power surges and lighting failures, which is crucial for both the driver and other road users. Thanks to the appropriate cable length and universal connectors, installation is quick and simple, while robust insulation ensures resistance to weather conditions, vibration, and mechanical damage .
