The Negativ Distribution Box is a simplified system to connect the terminals of the elimination of multiple electronic devices, such as mobile phones, car play, or others, safely to your bike, maintaining the original electrical system unaltered. The electrical devices require a power supply whose negative pole ( black) must be connected to the ground on the frame of the motorcycle. The problem is that in modern bikes, this can be difficult, the paint protects the whole frame, and it is not easy, or easy to find a safe point of connection. Our Negative Distribution Box solves these problems with ease. It connects directly to the battery and is positioned where there is more space in the bike, thus solving both the problem of chassis connections and limited space under the battery guards.
