This is how my switch boxes wire up different brands may have different colors I'm not sure

Red = Power
yellow/white = drivers front down
Green = drivers front up
yellow = pass front down
brown = pass front up
blue = drivers back down
green/white = drivers back up
black = pass back down
white = pass back up
