R55 Interpreting Fuse Panel Symbols

Interpreting Fuse Panel Symbols
So I'm trying to avoid having to run a #10 wire for 15A DC (+) from my boot in back up to the battery that would power a trailer light module from Tekonsha.
They say it's best to do this so module's powered 24/7/365. I can understand that, particularly if module needs to be "programmed" to interpret tail and brake light wiring signals coming in from the sensors the module takes its info from to then power the lights on trailer downstream.
BUT routing anything like a #10 wire so it's both protected and also doesn't disturb any of the factory wiring harness is a major PITA.
So if I can use the 12V (+) from the lighter socket in the boot, I think that would be acceptable. If I need to 'program' the trailer light module every time I hook it up that's less of a problem, at least until I can get a handle on where I'd need to route a direct-power wire from battery.
SO can anyone reading this thread interpret which symbol on my '13 Clubman's fuse panel might be for that lighter socket in back?
Or what the one for the 20A fuse @ F44 might be for? Can-bus electronics are newer than my decades-old brain can fathom.

Thanks Cristo, I had a hunch that was what it might be for.
Friend sent me this from his Bentley R56 service manual:
But not knowing made me ask.
If one looks at it as a "charging socket" as opposed to a cigarette / cigar lighter, then the symbol makes some sense.
That it's nearly as hard to take power from the fuse panel as from the battery has me thinking I'd be better off running that #10 wire supplied with the Tekonsha module as recommended. It's not that much farther to the battery now, is it?
Now I need to find where to get an idea of where I can pass a wire through the firewall someplace accessible... and find some key that explains what the wiring color codes are....
