Electrical wires and harnesses serve as the nervous system of the engine, distributing power and transmitting data signals. High-quality insulation is required to protect these conductors from engine heat, oil, and moisture. Corroded connectors or broken wires can cause intermittent sensor failures, improper engine timing, and communication errors between the vehicle's electronic control modules and mechanical components.
