After Market Head Unit
 

I own a 2014 tC and I recently put in a pioneer avh-x3600bhs head unit. I got everything to work except the fm/am radio. The problem is the antenna being a plastic wiring harness rather than a metal antenna jack, which is what I am used to. And I also purchased the axxess steering wheel control interface aswc-1 and I'm not too sure of the exact wiring that I need to do in order to make this work. If there's anyone that knows how to do either of of these that would be greatly appreciated.
