Harmony 650 on Vanilla Kodi install – can’t figure out the whole thing

I have installed Kodi 15.2 over a clean install of raspbian on RPi2 (I tried OSMC and LibreELEC but neither could pick my wifi so I gave up and went vanilla). I connected a DIY IR receiver directly to GPIO and configured lirc to extend where it “understands” that the remote is sending something its way (when I stop the lirc server and mode2, it will print some codes when I press buttons on the remote).

This is where I got stuck – I scanned through a lot of documentation on how to get things going, is there a simple description of the next steps I need to take to get going with my setup and Harmony 650 (I guess I could upload any other profile to harmony)? Some instructions refer to enabling the GPIO IR but I don’t seem to find any of these options in the kodi system/settings menus.

Appreciate your input. There are multiple instructions on how to get going with these but I am genuinely lost here.
