Help with modding argb hub

[magus7091]

I'd like to start by saying that the majority of the information I've needed is answered in a previous thread but as it's an old thread, the site recommended starting a new one. I'm trying to figure out information about an uphere rgb fan hub. This is the prior thread

 

But the question I have is regarding the unoccupied contacts on the sata power side. After a great deal of googling and looking at a few other hubs that use the same board, I can see that other iterations have the points occupied with a connector, but no answer as to what it does. The attached image from the previous post show the pads I'm referring to.

 

It's the Key, GND, D & G I'm trying to figure out. I'm wondering if they could be pwm related as I found a Chinese site that seemed to indicate that hub had fan speed control. Is there a way I can test to determine what function those pads have? I know my way around a multimeter and soldering iron, but I don't know exactly what I'm looking for. Can someone suggest what to try/look for? Thanks.

im going to guess the key is like a rest button and d and g is data and ground from the mb but it also looks like there parts missing of the pcb so w/e it was it probly wont work.

So the assumption would be that the D,G pins would communicate with the motherboard header, if the missing chip were actually attached?
