The electrical system connects all relevant components in the vehicle. The more complex the car is, the more complex the wiring harness has to be as well. A relatively simple cable was enough for the Goggomobil, but the size of the wiring systems has greatly increased over the years. More and more electronic components must be supplied with power.
In 1997, DRÄXLMAIER developed a functionally-integrated door module. The door for the BMW 7 Series was the first interior module that integrated all electrical and electronic functions of a door into a complete system. Shortly thereafter, BMW also ordered from DRÄXLMAIER the functionally-integrated center console for this model.
