Wiring harness and connectors

Dozens of meters of wiring run through an MX5 NB (1998–2000), connecting all the electrical systems. From lighting and sensors to windows, audio, and engine control: signals and power are routed throughout the car via wiring harnesses and connectors. Where moisture, vibrations, and age converge, malfunctions often occur precisely at connections, contact points, or in damaged wiring. A poor connection can cause a variety of symptoms that do not always point directly to the cause. When sensors and electronic control components within the system are functioning correctly, communication between all components remains reliable.
