The sun-roof power supply comes from the ignition-operated line
(INT/A) connected to relay
R1
protected by fuse
F13
:
both are contained in junction unit
B1
.
This line protects the circuit and leads
to sun-roof junction
D45
, which is also connected to earth
C15
.
The switch is therefore active when the
ignition is on (INT/A). The control unit controls engine movement
according to switch position.
