Just registered to give the answer:
The hardwire kit does not work for me because I want to use a powerbank for parking mode so that I do not drain the car battery and can record for a long time.
Btw: my viofo A119 V3 consumes 273 mAh (per hour) in driving mode and with h265 codec.
Prerequisite: you need to enable parking mode in the menu (e.g. auto event detection).
If GND is connected to USB pin 4 (ID) the cam will enter parking mode.
If VCC -> 5k Ohm resistor -> USB pin 4 (ID): the cam will enter driving mode/exit parking mode.
For this to work the cam must be first powered up in driving mode - this triggers the automatic switch by sensing the ID pin.
The switchover is instantaneous, not the motion detection based switching which also does not work.
I used three relays to perform the switchover from car battery while driving and powerbank when parked. If someone is interested I could provide a schematic.
Thanks to viofu. Based on the information provided above, I have used an even simpler wiring method described at:
