Wiring Systems


Today’s vehicles have a variety of systems smart controllers are responsible for. To make sure that communication between them can take place, a well-designed electrical harness is needed to meet requirements such as safety.

In a car s everal kilometres of wires form the entire on board network . It is kind of an analogy to the human nervous system, through which also electrical impulses flow. Most people don’t reali s e just how complex and elaborate the wiring system hiding in their car is… and of course, they don’t have to. This is where our company comes in.

What are vehicle electrical systems?

Vehicle wiring systems refer to the complex network of electrical wires, connectors and components found in vehicles. These systems are responsible for transmitting electricity and signals to various parts of the vehicle, including the engine, lighting, dashboard controls, entertainment systems and other electrical equipment.

Properly designed and installed wiring systems are essential to the reliable and safe operation of vehicles. They require careful planning, routing and protection to prevent electrical interference, abrasion or short circuits.   

How can you benefit?

By working with our company, you can receive support in developing your electrical harness from schematic to production. Our experienced engineers will do their best to ensure your vehicle functions optimally with a perfectly created wiring harness.

We base our work on our knowledge of various automotive processes (including VOBES). As a result, we are able to bring about an increase in the safety, performance and reliability of your vehicle. You can also be sure that we maintain a partnership with you throughout our collaboration and integrate seamlessly into your processes. Moreover, our activities are documented on an hourly basis so you can count on transparent pricing conditions from the beginning of your cooperation with us.

Development process of vehicle wiring systems

The process of creating vehicle wiring systems involves several stages
such as design, component selection, routing, harness assembly as well
as testing and consists of the following steps in brief:
(please choose an icon)

determine which components will be present in the vehicle and for which the wiring needs to be prepared.

determine (usually with the 3D department) the positioning of the components in order to assign the components to the corresponding systems (doors, bumpers, roof).

3D and 2D work should run in parallel during this phase. The 3D department prepares the layout of the wiring harnesses on the 3D model (it takes care of the routing and fixing of the wiring harnesses). The 2D department prepares the logic diagrams (electrology of the connections).

the two activities must then be merged and the technical documentation prepared for the wire harness supplier (for production). This usually involves a production drawing as well as connection and parts lists.

a test harness is prepared and feedback on corrections is given after the test. Tables and production lines are prepared.

after implementation of the corrections, series production takes place, which can also be changed during development by change management.
