The cabin wire harness is the key enabler of all comfort, safety, and control functions inside an agricultural vehicle. It connects dashboard instruments, HVAC units, lighting, sensors, infotainment devices, joysticks, and auxiliary controls, ensuring efficient power distribution and seamless data communication within the operator’s environment. Designed for reliability and customization, it guarantees ergonomic operation and driver safety under all working conditions.
Materials & Components
OEM S.r.l. manufactures cabin wire harnesses using premium materials selected to withstand the mechanical and thermal stresses typical of closed vehicle interiors:
- Cables with thin-wall insulation, high flexibility, and flame-retardant properties (PVC, TPE, halogen-free compounds).
- Connectors and terminals optimized for compact dashboards and confined spaces, including multi-pin systems, sealed plugs, and modular housings.
- Protective elements such as braided sleeves, acoustic insulation tubing, and anti-abrasion tapes to reduce vibrations, prevent noise, and extend service life.
- Switchgear and interface components (CAN-bus connectors, data lines, control switches) fully compatible with electronic architectures for modern tractors and harvesters.
Manufacturing Procedures & Techniques
Our production combines automation with tailored manual assembly, guaranteeing both accuracy and flexibility:
- Automated cutting, stripping, and labeling for accurate preparation of complex harness branches.
- Precision crimping and soldering, validated by pull-force testing and micro-section analysis.
- Twisting and shielding techniques to protect sensitive signal lines (e.g., CAN-bus, LIN-bus) against electromagnetic interference.
- Overmolding and sealing for connectors exposed to dust and moisture when routed outside the cabin.
- Ergonomic bundling and shaping, using templates and 3D fixtures to ensure easy installation and perfect integration in tight cabin spaces.
Cabin harnesses can be configured for:
- Dashboard and instrumentation clusters with multifunctional displays.
- HVAC systems including blowers, sensors, and control panels.
- Lighting circuits for interior and working lamps.
- Safety systems such as seatbelt sensors, roll-over detection, and alarm signals.
- Smart farming features, including GPS modules, cameras, telematics, and ISOBUS connectivity.
