its an module that is connected to the window switch. It will make it an exspress up/down switch.It can also be connected to the alarm (dont know which alarms) to roll up the window when arming the alarm. This costs $70. It allows you to contrl one window in 2 directions, or 2 windows in one direction. Theres another one, basically the same but can controll 2 windows in 2 directions.
Hope this helps
