When you unplug the factory amp there will be three connections that come out of the back. One of them does 2 the amp and has all the sound and stuff. And the smaller one, according to the diagrams I'm looking at, are the steering wheel controls. And the small orange one by itself is powered antenna. I don't know why I don't have a plug for that. What do people do here usually? I have an ASWC-1 but from what I've been reading, the ATOTO A6 I got has been doing SWC for people better by itself than with ASWC-1 in the mix. Be but even if I did use the metra Axxess SWC, I don't know how they wan expect you to connect the box since they don't give you connector like the car has...
