Holybro Pixhawk 4 PM07 Power Management Board

I have an S500 quad Copter X Frame that was fitted w/china clone Pixhawk 4. I now have a Holybro Pixhawk 4 w/the PM07 Power Management Board. I need 5v output from the PMB to power 4-LED’s, 1 under each Motor. PMB does not output 5v, it has to be powered from a separate 5v BEC, 5v UBEC or S2 battery. The 5v BEC I’m using comes from one of my ESC’s, the other 3 BEC’s will not be used. I’ve been over the PM07 Documentation & Diagrams, the “FMU Pwr out” shows’ No 5v output, as does the “CAP&ADC-in”…? My Question is "Where do I connect +/- for 5v coming from my ESC’s BEC…To get +/- 5v for my Lights…? And, Later…If I decide to add a Camera, where will I get my 12v for the Camera power & Gimble…? One other question, The Holybro Pixhawk 4 Flight Controller has 2 Power Brick Connections, the Instructions say connect to 1 power brick, if so , what is Power Two for…? Thanks in advance,
James…
