Rely on tested quality and order cable sets and individual connections online.

The cable route for power & signals

Cable harnesses and individual connections form the nervous system of your vehicle electrics – they connect lights, control units, sensors and actuators. A precisely designed cable system ensures that voltage and signals are transmitted without loss, which is crucial for the reliability of electronic components.

Variety in connection & repair requirements

Various repair kits and cable sets are listed in the store, e.g. cable sets for lighting units as well as repair or adapter solutions for control units. These enable targeted wiring or repairs if cables are defective or need to be adapted.

Cable set

What should you look out for when buying:

CROSS CUTS

The cable set should provide sufficient cable cross-sections and the required number of cores for your application.

PLUGS AND CONNECTIONS

Make sure that the connector shape and connection geometry match the existing system.

DISTRIBUTION

Choose cable sets of a length that matches the planned installation location so that the cables can be laid neatly and without tension.

Extreme loads and protection in truck cable systems
In the commercial vehicle sector, cable harnesses are not just simple conductors, but highly stressed components that have to withstand extreme environmental conditions. The massive vibrations of the chassis, the movements of the engine and the high temperatures in the engine compartment place permanent mechanical and thermal stress on the cables. Added to this is the corrosive environment caused by dirt, moisture and road salt. Truck cable harnesses must therefore have robust insulation and high-quality protective conduits to protect the wires from abrasion, short circuits and breakages, which would be fatal in continuous truck operation.

The role in data traffic and high-current supply
Cable harnesses in trucks must transmit both sensitive data signals and high current loads without errors. In the field of CAN bus communication, the integrity of the signal lines is essential for the error-free functioning of control units such as EBS, ECU or transmission control units. At the same time, the main cable harnesses must safely carry the high currents of the 24-volt system (e.g. for lighting, starter motor or the powerful air compressor). When purchasing, it is therefore important to ensure the correct cable cross-section and the quality of the cores in order to avoid voltage drops that directly reduce the performance of electrical units.

Tightness and connector quality for maximum availability
The weak point in the truck cable system is often the connectors. These must guarantee absolute tightness (high IP protection class) to prevent water and moisture from penetrating the contacts, which would lead to corrosion and contact resistance. In the truck sector, special, often multi-pole and lockable connectors are required that are protected against vibration and enable the fast, reliable connection of complex subsystems (such as the connection to the trailer). Choosing OE-quality replacement and repair kits with high-quality contacts and seals is the best guarantee for reliable vehicle electrics and minimizing costly, unscheduled downtime.

Expert Guide: Everything You Need to Know About Cable Assemblies & Individual Connections

Wiring harnesses and individual connections form the nervous system of a vehicle’s electrical system. They connect lights, control units, sensors, and actuators, and transmit power and signals. A precisely designed wiring system ensures that voltage and data are transmitted without loss—a prerequisite for the reliable operation of all electronic components.

In commercial vehicles, cables are exposed to constant vibrations, engine movements, and high temperatures in the engine compartment, as well as dirt, moisture, and road salt. They therefore require robust insulation and protective sleeves that shield the wires from abrasion, short circuits, and breaks—a critical factor in continuous operation.

Wiring harnesses must transmit both sensitive data signals and high current loads without error. In the CAN bus, signal integrity is essential for the operation of control units such as the EBS, ECU, or transmission control unit. At the same time, the main wiring harnesses carry the high currents of the 24-volt system, for example, for lighting, the starter motor, or the air compressor.

The weak point in the cabling system is often the connectors. They must be completely watertight (high IP rating) to prevent water from entering and causing corrosion or contact resistance. In trucks, this often requires multi-pin, lockable, and vibration-resistant connectors—for example, to ensure a reliable connection to the trailer.

Typical signs include electrical components that fail or operate intermittently, error codes caused by faulty signal transmission, voltage drops resulting in reduced power output from generators, as well as visible corrosion, chafing, or damaged insulation. Such defects can often be specifically remedied using repair or adapter kits.

The cable harness should have sufficient wire cross-sections and the required number of conductors to prevent voltage drops. Make sure that the connector type and connection geometry are compatible with the existing system and that the length is appropriate for the routing path, so that the cables can be laid neatly and without tension.
