does anyone know how to alter the window electricals to get it to wind-up on its own? my lancer will wind-down automatically after i hold down the button, but it doesn't do the same for the opposite.

I know that its a simple installation of a relay and maybe a few resistors, but i can't find any schematic of it on the internet. i know that there are people out there who have figured out the circuit, but they don't reveal it.
