Installation and Operation

Replacing an ignition switch is an operation that requires precision, but with care, it can be performed independently. Before starting work, disconnect the battery cable to avoid accidental short circuits or electric shock. Pay close attention to connecting the wires correctly according to their colors or markings; incorrect wiring can damage the engine's electronics. After installing the new SIERRA MP41040 ignition switch, test its operation by turning the key, ensuring the mechanism locks and unlocks smoothly without resistance.
