High performance manufacturing processes include automatic data acquisition systems for continuously monitoring sensor outputs to ensure they respond with appropriate voltage output within a specified frequency range. Effectively restoring your engine and avoiding detonation or noise is crucial for high-quality durability, which is why our sensor wiring harness is designed with tin plated and solid brass terminals to ensure excellent conductivity. At the same time, it helps resist corrosion of wiring harnesses, ensuring a longer service life.
