PM07 with Holybro X500 V2 ARF Kit

I ordered the Holybro X500 V2 ARF Kit together with the Pixhawk 6C + PM07. The ARF kit includes the PDB02-V1.2 board, which allows me to connect the four rotors to this board + the battery. However, it does not provide a connector to power the Pixhawk. So I thought I could solve this with the PM07 board.

However, this board does not have these pre-installed connectors for the rotors. My idea now is to cut them from the ARF kit and solder them to the PM07 board (V++ and GND). Is this the right approach? I couldn’t find anything useful so far regarding this problem. Thank you very much!
