Electrical Zones
The whole electric system is divided up into a number of electrical zones.Each electrical zone consists of a sub-system, which is a complete harness supplying different components. The electrical zone is in its turn connected to the rest of the electrical system by means of large connectors. By having a small number of large harnesses, the result is fewer connectors and. accordingly, fewer fault sources.
