Hello.
I want to install an anti-rat repeller and I want it to work only when the ignition is off (or\and the alarm is on).
As you all know, we have the following fuses in the dash panel:
2 Airbags

4 Front camera for assist systems
5 Exterior lighting of the rear of the vehicle
6 Interior lighting
7 Front seat heating
9 Window controls (left side of the vehicle), central locking (left side of the vehicle), left wing mirror (heating, folding, glass position adjustment), electric child lock (left side of the vehicle)
11 Towing bracket
13 Central locking (rear doors and boot lid), windscreen washers, headlights tilting function
14 Music amplifier
17 Rear radar sensors, Park Assist, Parking Aid
18 Steering wheel lock, KESSY (keyless locking), contactless operation of the electrically operated boot lid
19 Instrument cluster, emergency call, online services

26 Window controls (right side of the vehicle), central locking (right side of the vehicle), right wing mirror (heating, folding, glass position adjustment), electric child lock (right side of the vehicle)
27 Passenger's seat belt tensioner

29 Towing bracket

41 Data bus
42 Gearbox control, gearbox mode display
43 Air conditioning at the front, air conditioning at the rear, rear window heating
44 Front interior lighting, parking brake, rain and light sensor, lights control, alarm system, diagnostic socket, dashboard button panel.
45 Control lever under the steering wheel

And also under the bonnet:

I think the fuse 40 is a good candidate. Also, fuse #18 seems to be a good option.
Do you know whether this fuse is powered when the car is on (ignition is on)?
Or maybe you have another idea which fuse to use?
