I need help with mapping buttons on this controller.

I lost the manual for this controller, I'm almost certain it's from a third party. I want to know how to map buttons to the buttons on the back but I can't remember and I lost the manual. I can't find anything besides a listing on eBay for this thing and every time I try to look up how to map buttons it gives me a tutorial for a completely different controller. It's not letting put more than one image so I can try to describe the front of the controller. It looks like a basic Xbox controller but no Xbox button, a button with three lines and one with two squares at the top and two more buttons below them, one looks like a sun that I know can change the brightness of the LEDs on the controller but it might be able to do something else too I'm not sure. The other button looks like a rectangle without the top line and an arrow pointing up that starts on the bottom line of the rectangle. In the center of the controller is a button with a house on it, it's the equivalent of the Xbox button. And in the bottom center are four dots in a column that lights up when it's turned on.
