2004 audi s4 radio problem

Does anyone have the radio wires for a 2004 audi s4. I no the constant 12V is RED / blue and ground is brown but im having trouble finding the others. thanks

Audiovox has no info for the S4, but they do have the following info for the S4 Avant, 07 model.  This is the only one I could find that had the same constant and ground info you have.

	Battery		RED / BLUE		(+)		RADIO HARNESS
	Accesory
	Ground		BROWN		(-)		RADIO HARNESS
	Illumination
	LF Speaker (+)		BROWN / GREEN
	LF Speaker (-)		BLUE / YELLOW
	RF Speaker (+)		BROWN / BLUE
	RF Speaker (-)		GREEN/ BLUE
	LR Speaker (+)		BROWN / YELLOW
	LR Speaker (-)		RED / YELLOW
	RR Speaker (+)		BROWN / BLACK
	RR Speaker (-)		RED / GREEN

I bought the Metra amp wiring harness and it didnt fit
