Daikin Sensira FTXC-E series wiring / S_DGC port wiring

[redecs]

Hello!

I'm am the not so lucky owner of two new Daikin FTXC-E series AC units that come with an included wi-fi adapter but lacks the S21 connector on the board.

Took a peak at the indoor unit motherboard and notice the include wi-fi adapter (the one with thin black wires) plugs into a port label S_DGC.
There's also a S21 port but without a header.


I've also found a wiring diagram, included here: #809.

Anyone else countered a similar unit? Had any luck wiring a Faikin to it?
Thanks!
