Truck Lighting Wiring Looms, Fuse Boxes & Fuses

The Wiring & Fuses category brings together the electrical hardware that keeps your truck lighting working reliably – wiring looms, connectors, fuse boxes and individual fuses for modern European lorries. Instead of guessing with universal cables, here you can buy used OEM lighting looms and fuse carriers removed from late-model donor trucks and listed with clear photos and OEM numbers.

All parts are sourced and dismantled by VRA Truckparts, a UK-based specialist in used OEM truck parts for Volvo, MAN, DAF, Scania and Mercedes-Benz vehicles. Trucks are broken in-house in Essex following a structured Dismantling & Quality Process, so harnesses and fuse boards are stored dry and protected before listing.

What wiring and fuse parts are in this category?

This section focuses on electrical components that power and protect the lights in the Lighting range, including:

• lighting wiring looms for front and rear lamps, including headlight and fog light harnesses;
• section looms for bumpers, cab roofs, rear chassis and marker lights;
• fuse boxes and fuse carriers related to lighting circuits;
• fuse holders, relay bases and small junction blocks for lamp feeds;
• connectors and pigtails for headlights, fog lights, marker and work lamps where supplied complete;
• other small but critical electrical parts that sit outside the main Ignition, Charging & Starting category.

Complete headlamps, fog lights and tail lights are listed separately under Headlights , Fog Lights and Reverse & Tail Lights , while work lamps and speciality modules are grouped under Other Lighting .

Why genuine OEM wiring looms and fuse boxes matter

On modern Euro 5–Euro 6 trucks, lighting circuits are integrated with CAN-bus electronics, body control modules and diagnostic systems. Using the correct OEM harness and fuse layout helps to:

• avoid CAN-bus errors and bulb warnings caused by incorrect resistance or loading;
• ensure proper cable sizing, insulation and routing around the chassis and cab;
• match connector types and pin-outs to existing lamps and control units;
• reduce the risk of intermittent faults from poor-quality aftermarket wiring.

A used OEM loom or fuse box from a known donor truck is often a better solution than building an improvised harness, especially when repairing fleets where downtime and repeat faults are costly.

Truck brands and donor vehicles

VRA Truckparts specialises in late-model European heavy trucks. Many wiring and fuse components in this category come from:

• Volvo FH and FM long-haul and regional trucks;
• MAN TGX and TGS tractor units and rigids;
• DAF XF and XG series vehicles;
• Mercedes-Benz Actros and Atego;
• Scania R- and S-series and other modern HGVs.

For examples of current and past donor vehicles, visit Trucks We Dismantle. Matching your wiring or fuse box to the same generation and cab type as your truck can make installation much easier.

How VRA Truckparts handles wiring & electrical parts

Harnesses and fuse boards are removed and stored as part of our Dismantling & Quality Process. During dismantling and listing we:

• avoid cutting looms unnecessarily, preserving OEM connectors where possible;
• inspect outer insulation and corrugated conduit for damage and heavy wear;
• check fuse boards for signs of overheating or water ingress;
• photograph the exact loom or fuse box, including labels and connector views.

Each listing describes the donor truck and shows any repairs or taped sections, so you can decide whether a part is suitable as a direct replacement or mainly for testing and spares.

Checking compatibility before ordering

Wiring looms and fuse boxes are often specific to:

• cab type (day cab, sleeper, high-roof);
• chassis layout and wheelbase;
• lighting specification (halogen vs LED, extra work lamps, marker packages);
• market and regulatory requirements.

Before ordering, we recommend following the guidance in How to Find the Right Part and Compatibility & VIN Policy, then contacting VRA Truckparts with:

• your truck registration or full VIN;
• make, model, year and Euro class;
• any numbers from the existing loom or fuse box and clear photos of the connectors.

Our team can help you cross-check the wiring or fuse component against current stock in the Lighting and Ignition, Charging & Starting sections where relevant.
