New stereo/ Axxess swc problems

[Kbien]

Hello guys I’m having a issue with axxess swc it’s telling me to use pin 14 or 28 but if you look at the factory harness there are no pins on the harness for 2015 sonic, would anyone know the color code wires I need for the steering wheel controls

The aswc-1 gets wired into the other metra adapter that comes with the dash kit (99-3012G).

I think the model number that ends in LC just does not have the wires ready/plug-n-play for the aswc-1,
you have to wire it together yourself.
