Mercedes Actros MP4 Cabin Full Wiring Harness Loom 0005466401 0066501343 Euro 6 Wiring & Fuses

Description:
This listing is for a genuine Mercedes-Benz Actros MP4 Euro 6 cabin wiring harness loom, a complete cab cables set suitable for tractor units. The loom includes multiple bundled wiring branches for dashboard, doors, roof, chassis interface and engine/exhaust connections, with the central plastic junction / distribution box clearly visible in the photos. OEM references 0066501343 and 0005466401 are associated with the Actros MP4 cab wiring harness electric installation in professional truck parts catalogues and dealer adverts, confirming correct identification for this component.

The harness is designed for 24V commercial vehicle electrical systems and carries power and CAN-bus / signal lines between ECUs, sensors, switches, lighting and auxiliary equipment throughout the cab and forward chassis area. It features OEM Mercedes multi-pin connectors, sealed plugs and earth points, with PVC-insulated copper conductors and protective corrugated sleeving. This type of loom is critical for reliable operation of all electronic systems in the Actros MP4 Euro 6 range, including lighting, instrumentation, comfort functions and safety equipment.

This used harness was removed from a fully operational Mercedes Actros MP4 Euro 6 truck and was functionally checked on the vehicle prior to dismantling to confirm that major electrical systems worked correctly. After removal, key branches and the junction box were visually inspected for damage; no burnt areas or severe insulation failures were found. Condition is graded as B: there are external signs of use such as dirt, oil stains, worn sleeving and minor scuffs from routing around the cab, and some minor clips or small connectors may be missing or broken, so professional installation and careful inspection before fitting are strongly recommended. The loom is supplied exactly as pictured, without additional control units, sensors or mounting hardware.

Compatibility is primarily with Mercedes-Benz Actros MP4 Euro 6 tractor units and rigid trucks that use the same cabin platform and wiring configuration. Because Mercedes used different looms depending on cab type, wheelbase and equipment level, buyers must always match all OE numbers (0066501343, 0005466401 and listed cross references) with their existing harness and, where possible, verify by VIN with a dealer or specialist. Incorrect application can lead to malfunction or damage to vehicle electronics.

Installation of a complete cabin wiring harness is a complex task that should only be undertaken by experienced commercial vehicle electricians. In many cases interior trim, dashboard and modules must be removed and refitted. After installation, system diagnostics with Xentry or equivalent are recommended to clear any stored fault codes, perform coding or configuration and verify that all electrical consumers operate correctly. The harness itself does not require programming but connects to ECUs that may need coding.

The part is sold with a 3‑month warranty covering proper electrical function when installed correctly and not modified. As a genuine used OEM loom it offers a cost‑effective solution compared with a new harness from Mercedes, ideal for repairing accident or fire damage or converting a donor cab.
