i picked up my s2k a month ago or so and when i picked it up the guy had the seats swapped out of it. With the seats came the head rest speakers. It would have been nice if he had the wire harness so acually plug them in but he did not. so i ask if anyone has or can tell me where to get these wire harnesses. Also since the car didnt come factory with these speakers do i have to modify the stereo at all or is it just a simple plug in thing?
