Pin out for 7 pin Pollack connector

I have only seen a +12V power on center on a 6 pin....not a 7 pin
The differences I have encountered on 7 pin is the positions on a 'flat blade' and a 'round pin' connectors.
Both have the +12V at the top right (1 o'clock) position & running lights at top left (11 O'clock) position
The other blades/pins are completely different
Turn lights are opposite positions
Brake controller and reverse lights are swapped
Grounds are opposite positions
As for key on vs always hot......I prefer HOT as I have other devices I plug into truck receptacle and don't like having to turn key on to use
ON EDIT: the 'auxiliary power' terminology seems to show up when looking at trailer vs vehicle connections......same as +12V power on vehicle side.
