Goal
The Gen2 platform models power the 12V system from a DC-DC 12V Converter that is only enabled on key-on via signaling from the MBB.
Some 12V accessories for security and other purposes benefit from an uninterrupted power supply.
Applications
  • An embedded system Arduino etc.
  • implement keyless unlocking
  • antilock devices
  • bike locators
Always-On 12V Power Supply
Burton's howto with a video and disclaimer
Always-On 5V Power Supply
Two lines to the DC-DC converter are always on at main battery voltage (see Burton's wiring diagram).
Doctorbass observed in the above thread that many USB charging adapters can run on DC as easily as AC.
It may be risky to try this.
