The Evolution of Automotive Electrical Systems

TLDRThe automotive electrical systems have evolved from basic wiring to complex multi-pin connectors. Early systems used cloth-covered wire, which evolved into stranded wire and eventually synthetic polymer wire insulation. Connectors progressed from solder-on ring terminals to bullet terminals and crimped connectors. The introduction of plastic-based connectors made automotive electrical systems more cost-effective. The advancement of solid-state electronics brought new functionalities to vehicle electrical systems.
