The fuses and relays are spread over different bmw power distribution boxes in their vehicles. Some examples of possible installation locations are shown below. The distribution boxes can be incorporated in the luggage compartment, in the engine compartment and behind the glovebox. Even a combination of all three installation locations is possible, such as e.g. E65/E66.
In the E7x and F0x vehicles, there are two separate distribution boxes. The front distribution box is near the glove box and the rear distribution box is on the right-hand side of the luggage compartment. The following graphic shows the arrangement of the most important components of the power supply system in the F0x.
