Detailed Process Description
- Requirement Analysis The vehicle electrical architecture, components, circuits, current requirements, environmental conditions, and installation locations are reviewed before harness development.
- Wiring Harness Design A wiring harness design is prepared according to circuit requirements, connector locations, wire lengths, branch points, and vehicle architecture.
- Wire and Material Selection Suitable conductors and insulation are selected according to electrical load, operating environment, flexibility, temperature, and application requirements. Copper wiring harnesses are commonly used where suitable conductivity and flexibility are required, while aluminum wiring harnesses may be considered for selected weight-sensitive applications.
- Wire Cutting and Preparation Wires are cut to specified lengths and prepared for terminal and connector assembly. Identification and labeling can be applied according to the circuit design.
- Terminal and Connector Assembly Wiring harness connectors and wiring harness terminals are assembled using suitable methods. Crimp connections in the wiring harness are formed to establish secure electrical and mechanical connections.
- Harness Branching and Routing Individual wires and branches are organized according to the vehicle layout. Wiring harness routing ensures suitable placement while maintaining clearance from moving parts, heat sources, sharp edges, and other potential interference points.
- Protection and Looming Wiring harness sleeves and looms are applied where required to provide organization and protection. PVC insulated wiring harnesses can be selected according to application requirements, while heat resistant wiring harnesses are used where higher-temperature environments require suitable materials.
- Specialized Circuit Integration Sensor, lighting, HVAC, airbag, ABS, infotainment, and engine control circuits can be integrated into the appropriate harness assemblies. Shielded wiring harnesses may be used for selected circuits where protection against electrical interference is required.
- Inspection and Testing Continuity, connectivity, insulation, terminal placement, polarity, and other relevant parameters are checked during wiring harness testing.
- Final Quality Verification The completed harness is inspected against drawings and specifications before packaging and integration into the vehicle assembly process.
