Body Wiring Harness

Body wiring harnesses are pre-assembled electrical distribution networks for vehicle body systems, including lighting, power windows, door locks, and infotainment. Installed within the vehicle’s body structure—typically routed through cavities and protected by sheathing—they deliver power and signal circuits. Construction utilizes multi-conductor cable assemblies, sealed connectors, and often incorporates service loop slack for maintenance access. Harnesses are vehicle-specific, differing by model, options, and market regulations. Modern designs increasingly integrate CAN bus and other data network wiring for advanced vehicle functions.
