The field at the top of the diagram can be «flooded» in gray, it displays the internal layout of the mounting block. Lines with symbols «30», «15», «X», «31» etc. correspond to the terminals of the ignition or instrument switch and starter. The numbers placed in a square frame on a black background and placed next to the control and relay units correspond to the device field number in the mounting block. Wire breaks indicate wire cross section in mm2; the numbers in a square frame at the end of the wire correspond to the number of the route along which the wire is laid.
