Additional elements
Two additional blocks are located in the engine compartment on the left side (shown by arrows)
Since the covers on the additional relay blocks are the same and the inscriptions on the relay and fuse assignments are duplicated, the specific purpose of a particular element can only be known experimentally.
In the passenger compartment
The distribution box is located to the left of the steering column at the end of the instrument panel. Remove the trim to gain access.
