Overview
Cabin interior and IFE wiring runs the length of the fuselage through tight overhead and seat-track channels, so every gram and every millimeter of routing space is engineered against strict weight and certification requirements.
Design & Construction
Lightweight, Long-Run Architecture
Conductor gauge and jacket materials are selected per run to minimize weight across long cabin trunks without compromising MIL-DTL-27500 performance.
Seat & PSU Interconnect Design
Modular connector zones at each seat-track and passenger service unit position simplify cabin reconfiguration and MRO harness replacement.
Manufacturing Process
Manufactured under AS9100D quality system controls with IPC/WHMA-A-620 Class 3 workmanship and full material lot traceability from certified aerospace wire suppliers.
Typical Applications
- In-flight entertainment (IFE) system wiring
- Cabin lighting and signage harnesses
- Seat power and USB/data cabling
- Galley and lavatory equipment wiring
- Passenger service unit (PSU) interconnects
Common installations include In-flight entertainment (IFE) system wiring, Cabin lighting and signage harnesses, and Seat power and USB/data cabling, where flight-critical reliability and stringent weight optimization are the primary design drivers. The same base design can also be adapted for Galley and lavatory equipment wiring and Passenger service unit (PSU) interconnects with minor changes to connector type or cable length.

Customization & Lead Time
Standard lead time for the Aircraft Cabin Interior & IFE Wiring Harness is 8–10 weeks prototype (AS9102 FAI), 4–6 weeks production. Connector type, cable length, and conductor configuration can be customized to match your exact application, including MIL-spec connector alternatives and shielding options for specific avionics or airframe integration requirements. Contact our engineering team with your drawings or requirements for a project-specific quote.
Why XinHarness
Cabin and IFE harnesses run on the same AS9100D-certified lines as our avionics and airframe programs, giving cabin integrators a single certified source for interior wiring.
