A wire harness, in general, is a bundle of electrical wires or cables, along with connectors, terminals, and other components, organized together to transmit electrical signals or power. In the case of JST wire harnesses, the focus is typically on compact, reliable connectors that facilitate quick, secure connections in tight spaces.
