Industry Snapshot
Key metrics for the motor vehicle electrical and electronic equipment manufacturing industry.
Industry Definition & Overview
Motor Vehicle Electrical and Electronic Equipment Manufacturing (NAICS 336320) encompasses establishments primarily engaged in manufacturing electrical and electronic equipment for motor vehicles and internal combustion engines. Products include wiring use assemblies, ignition systems, alternators and generators, starter motors, voltage regulators, instrument clusters, engine control modules, body control modules, and vehicular lighting. The U.S. Census Bureau[5] classifies this industry under motor vehicle parts manufacturing.
Roughly 575 active businesses employ an estimated 64,700 workers in this industry. Wiring use manufacturing employs the largest share of workers, as use assembly remains labor-intensive despite partial automation of terminal crimping and connector insertion. A typical passenger vehicle contains over 1,500 feet of copper wire organized into multiple use branches that route through the vehicle body structure. Electronic control module production requires surface-mount technology (SMT) assembly lines, environmental stress screening, and extensive functional testing.
Vehicle electrification has expanded the scope of this industry considerably. Battery management systems, onboard chargers, DC-DC converters, and electric drive inverters for hybrid and battery-electric vehicles fall within this classification. Advanced driver assistance systems (ADAS) including radar modules, camera systems, and ultrasonic sensors represent fast-growing product categories. Tier 1 automotive suppliers including Aptiv, Yazaki, Sumitomo Electric, and Robert Bosch dominate wiring use and electronic module production through long-term OEM supply contracts. Quality systems must meet IATF 16949 automotive quality management standards, and electronic components undergo automotive qualification testing per AEC-Q standards for reliability under extreme temperature, vibration, and humidity conditions.
