Metra 70-1784 for the non amplified, Metra 70-1787 is the amplified version.

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
