The circuit for the seat lifting is controlled by the relay
J61.
This is supplied by the direct line for the maxifuse
J/B2 of B5.
The energizing
of the coil, supplied by the line controlled by the ignition (INT/A)
protected by the fuse
B27, allows the supply of the seat
lifting switch H69, through the line protected by
the fuse B21 (which also protects the wiring for
the mini bar).
The driver's seat lifting switch
H69 is
lit up by a special LED.
The operation in one direction or the other
of the switch
H69 determines the direction of rotation
of the driver's seat lifting motor N39 by providing
the motor with an earth or a supply.
