This main wiring harness is suitable for the Renault R4 from model years 1983 to 1992. The harness provides the central electrical connection between ignition, lighting, dashboard, charging circuit and other consumers. Connections and lengths match the original vehicle layout and the specified Maten [PW1]. The outer sheath protects the wires against friction and heat in the engine bay and along the body. Plugs and cables are grouped according to the vehicle layout, so the electrical functions remain clearly separated. The harness supports an orderly bundling of power supply and signal transmission within the vehicle.
