As long as it is a newer model sony the speaker colors are: left front: white. left rear: green. right front: gray. right rear: purple. The black stripes are your negatives, solids, positive.

For Sony radios you need an aux Bus adapter called the Sony XA 300. It works with the Bus IN RCA, and there whould also be another plug spot for the Bus power and signal interrupter. That is how the Sony knows to access that port.
