reaches pin 6 of connector A by means of the line coming from the
switch for the steering column switch unit

, protected
by the controls illumination fuse
F1
of the additional fuse
box
B98
; the radiophone controls are therefore lit up when
the lide lights are switched on.

is earthed (

are connected to the microphone P26 by means of a suitably screened
