I only have a partial in my book.
Red - ground
Yellow/black - fuse 11 power
Lt.Green/yellow- fuse 8 memory power always on
Orange/black - LCD power from light switch
Lt.Blue/red - Fuse 10 illumination power
So it looks like there is one ground and 4 power in, plus probably 4 more wires for speaker out which are not listed in my book.
