I found a device that is located down and to the left of the steering wheel. When I inspected the device I noticed that it has a green push button with a plus sign on it. It is connected to several wires of different colors. Also has a single green wire that has been cut. And beside that device is another one, that has a push button on the inside as well. I dont know for sure, but the devices look as if they are aftermarket, due to the looks of the way that they have been installed. Any advice or information is greatly appreciated.

This is the one with the green push button.

This is the one that, when you remove the top of the box, there is a black push button inside.
