help with Arepro harness for steering wheel controls??

[bartsau]

So I finally bit the bullet and picked up a control harness from autobarn. Along with the alpine patch harness. Connected it all up the existing harness behind the alpine head unit. I used connectors however plan to solder it. Problem is though I still have no steering wheel controls :(

Has anyone else fitted an au2/3 with this harness and managed to get their steering wheel controls working?

Or is it most likely my steering wheel controls wouldnt work even with a factory headunit as something is wrong with them? I do have working cruise control buttons....
