Simple. Take your door panels off, then disconnect your window switches. Take your battery and 2 pieces of wire with both ends stripped and attach 1 end of each wire to a terminal (1 to positive, 1 to negative). The easiest way is to tape them to the terminal using electrical tape. Next, start playing with postive and negative combinations on the connector that would connect to the window control switch. Once you find the right combination, the window will move either up or down, depending on the combination. I had to do this and it took me only a minute to figure out the right combination of ground and hot to get the window to do what I wanted it to.
