K&S TECHNOLOGIES offers you a solderless heat-shrink wire connector kit using a heat-activated low-temperature soldering system, enabling you to make solid, watertight electrical connections without the use of a soldering iron, greatly simplifying repairs and installations on motocross harnesses, while guaranteeing excellent resistance to water, dust and vibration thanks to a thermo sheath that shrinks to protect the junction and ensure reliable conductivity in the most demanding off-road conditions.
