Technical Characteristics of the Door Harness

This harness belongs to the Cables, Harnesses, and Connectors group, meaning it is constructed for stable transmission of power and control signals in the demanding environment of a car door. The connectors used are matched to the factory sockets of the body's electrical system and the modules located in the door, facilitating plug-and-play installation without the need for soldering or creating adapters.

The arrangement of wires, segment lengths, and branching points are in accordance with the original manufacturer's design, minimizing the risk of chafing, kinks, and stress during repeated opening and closing of the door. This ensures the harness supports the proper functioning of comfort and safety systems in this part of the vehicle.
