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 with the logic described above and controlled by the Body Computer M1 pin 14 of connector F.The energizing of the two relays, with the consequent supply of the two heater resistances O40 and O41 takes place via the switched 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 light up the LED located inside the switches I65 and I66 signalling that the heating is activated.
