Heavy drone Pixhawk Wiring

Hey guys,
Here are the parts that I’m using:

  1. Battery : 35000mAh, 50.4V
  2. Motor : T-Motor P80 KV100, 48V
  3. Communication : XLRS Module
  4. 2 Servos for payload mechanism
  5. SIYI ZT6 Mini
  6. Holybro Pixhawk 6X Pro

I have added all the necessary sample wiring diagrams, can somebody please help me with Power Supply module, PDB … etc, it is very hard to understand the wiring
