Need help with power window wire colors

[tumesinine]

So i decided to create new switch for passenger side power windows (since old one didn't work at all) but i dont know which wire does what.

So far i know that:
green/gray is for illumination
red/yellow is always +12.75V

unknow ones:
red/white
2x brown ones, probably one is ground but dont know which.

can someone fill the gaps?

Okay found it out by testing.
Both browns are ground, when you connect red/white with ground the window will go down, if you connect the same wire with +12V the window will go up.
