The power supply for the two seat relays
J62A and J62B comes
from the line controlled by relay T13 and protected by fuse F45,
both housed in the junction unit under the dashboard B2.
The services relay
T13 is energized according
to the logic described above and controlled by the Body Computer
M1 pin 14 connector F.
The energizing of the two relays, with the
consequent supply of the two resistances for the heaters
O40
and O41
takes place via the switches
I65 and I66.
The switches
I65 and I66 are, in turn,
supplied by the ignition-operated line (INT) for fuse F49 of the
junction unit under the dashboard B2.
The positive energizing command for the
relays
J62A and J62B also lights up the LED inside switches I65
and I66.
to signal that the heating is activated.
