Overview
Body control and lighting circuits combine bus communication with switched power in a single sub-harness: headlamp and taillamp feeds, door module and switch panel wiring, and the CAN/LIN links that tie it back to the body control module.
Design & Construction
Bus & Switch Circuits
CAN, CAN FD, and LIN bus wiring is routed alongside switched power circuits for lighting and door modules, with connector pinouts matched to the customer’s BCM and module drawings.
Lamp & Connector Sealing
Exterior lamp connectors are sealed to IP67 with UV-stabilized jacketing for engine-bay and exterior routing, while interior lighting and switch circuits use standard automotive TXL insulation.
Manufacturing Process
Assembled on IATF 16949-certified lines with the same crimp-force monitoring and PPAP documentation used across our automotive production, with 100% continuity testing before packing.
Typical Applications
- Headlamp and taillamp harnesses
- Interior lighting and switch panel wiring
- Door module interconnects
- Body control module (BCM) wiring
- CAN/LIN bus sub-harnesses
Common installations include Headlamp and taillamp harnesses, Interior lighting and switch panel wiring, and Door module interconnects, where vibration resistance and long-term durability under continuous thermal cycling are the primary design drivers. The same base design can also be adapted for Body control module (BCM) wiring and CAN/LIN bus sub-harnesses with minor changes to connector type or cable length.
