Hi Simon, It has a Orange/Black wire to support Steering Wheel Key Controls, but dont ask me where to connect this wire to the Car loom?

Is there two wires from the BMW loom for SWC, Blue/Purple for output and Blue/Orange is earth? I think.

I was not brave enough to try it out, so if anyone can confirm if you just connect the Orange/Black wire from the 2Din ISO harness, to the Blue/Purple wire from the cars loom.

Then what do we do with the Blue/Orange earth wire? (connect to earth I suppose).
