The fuse and relay boxes (342a and 342b) in the engine bay form a single unit.
The fuse and relay box for the dashboard is divided into two separate units:

All fuses are located in the fuse boxes. Only the relay for the passenger seat is not located in one of the relay boxes (it is located in the seat).
General
The fuses are of the blade fuse type. Together with their connection sleeves, they give a much lower voltage drop than the older types of fuse. They are
also much more resistant to corrosion.

Checking blade fuses
Each blade fuse has two test sockets to enable it to be checked while still in the fuse box. If there is power present in both sockets, the fuse is functioning
normally.
