The signal for activating the side lights reaches the ignition switch H01 (STAZ) connector B pin 4 from the steering column switch unit H05 when the latter is switched so that the circuit between connector B pin 5 and connector B pin 6 is closed. The supply reaches the steering column switch unit H05 from the fuse F32 housed in the junction unit under the dashboard B02 and from another fuse F1 contained in the engine compartment junction unit B01 .When the ignition switch H01 is in the STAZ position, the body computer receives a supply from H01 (POS) to activate the front and rear side lights and the no. plate lights via the junction unit under the dashboard B02 pin 2 connector E. The supply for the front light clusters F10 and F11 arrives from pins 40 and 30 connector C of the body computer, respectively; and for the rear light clusters F30 and F31 from pins 5 and 6 of connector A. The supply for the no. plate lights F50 and F51 is protected by fuse F51 located in the junction unit under the dashboard B02 .The body computer M01 is involved in supply the ''side lights on'' warning light in the instrument panel E50 via connector F (pins 31 and 36).The body computer is supplied via pin 11 connector E of the junction unit B02 from the ignition switch H01 (INT) or via a line protected by fuses F53 and F1 housed in junction unit B02 and junction unit B01 , respectively and, lastly, directly by the battery via protective fuse F1 in the engine compartment junction unit B01 .The supply lines arriving from the junction unit B02 via pin 11 connector E and pin A connector C also supply the instrument panel E50 via two lines protected by fuses F37 and F53 .Pins 8 and 9 connector D of the body computer are connected to earth.
