i copy and pasted this from another members post  , sorry i cant remember who ..

red = switched positive(ignition on)
orange = constant positive
yellow = positive when lights on (for illumination)
black/green = left rear speaker
green/red = left rear speaker
black = should have been earth but had no connection so had to make my own earth
grey and green/grey = right front speaker
white and red/white = left front speaker
