So, I’m having a hard time finding the information in 1 place.
This is the best post I could find in regards to modifying the firmware to add Aux:

There’s a unused capacitor and resistor right above the T85 chip that you remove and you use the resistor pad for Aux + and I typically solder the Aux - to the FET.
Edit: I found my Imgur post with pictures of the mod
