Hi,
This is what the fiat factory manual says about the cigarette lighter.
"The vehicle is equipped with a front power point and a cigar lighter housed in the middle of the facia next the radio and next to the ashtray respectively. The operation of both is controlled by dedicated relays and protected by fuses located in the underfacia control unit. The direct battery power supply is enabled only with the ignition key ON (INT/A). This strategy has been adopted to provide the engine with maximum power during ignition, due to the high potential power uptake by appliances connected to the point."
It also gives the following.
"The power supply to cigar lighter P050 is protected by fuse F44 housed in underfacia junction unit B002, and is governed by relay T12, also located in the junction unit.
When the ignition switch H001 is turned ON (INT/A), relay coil T12 is excited to deliver power to cigar lighter P050 - pin 2 -.
The power supply to power point P051 is protected by fuse F53 housed in underfacia junction unit B002, and is governed by relay T01, also located in the junction unit. When the ignition switch H001 is turned ON (INT/A), relay coil T01 is excited to deliver power to cigar lighter P051 - pin 2 -.
The coils of both relays are served by a line protected by fuse F31 and supply power directly from the battery, via a line protected by fuse F01, housedin engine bay junction unit B001.
Cigar lighter P050 and power point P051 come with internal lighting - pin 3 - that comes on when the side lights are activated. The activation input comes from short-circuit junction D097C - pins 5 and 7 -, connected to ignition switch H001 (POS)."
From the above, it would appear that you could bypass the appropriate relay/relays to have both sockets live constantly.
Keep well,
Torq
