I just built a 5" 6s quad. The FC and ESC are working, I'm spinning motors with betaflight, and the Caddx Vista is paired to the goggles and remote. I've also caliberated the Remote so it would seem everything is working thus far.

My issue is not getting the remote to respond in betaflight. As far as Configuration and Ports, I'm completely over my head. Not sure what to set for my receiver mode, or what modes I need. 
I guess I thought I could look up each step along the way, but I'm struggling all things Betaflight right now.

Sorry, I'm not even sure what questions I need to ask. Any video I watch, someone has a slightly different setup so I cannot plug and play.

I have a Speedy Bee f405 FC
T-motor V45A V2 ESC
Caddx Polar vista
DJI fpv Remote mode 2
DJI fpv goggles V2

My FC to ESC wiring diagram is attached. The vista plugged straight into the FC
Sorry this is such a vague request, but any Betaflight help would be great
thanks!

   

Can you please run the "dump", "diff all", and "status" commands in the Betaflight Configurator CLI tab and copy/paste the results back here.
