A used OEM Electric Radiator Fan Wiring Harness for the Audi S4, part number 8E1971725B (also replaces 8H1971725). This wiring harness connects the electric radiator fan to the vehicle's electrical system, managing fan speed and activation. On the 4.2L V8 (4163CC) engine, a failing harness can cause the fan to run erratically or not at all, leading to potential overheating.
