Does anyone have any experience with this steering wheel control module? I have it wired correctly I'm sure. Pink wire to pin A1 pink wire. Red to red and black to black. The single steering wheel control wire from the head unit to the pink wire, and the 3.5mm jack plugged into the head unit. I tap the volume up button and the light will turn solid red, which they say is the sign that it has detected and programmed. However, once it turns red, nothing happens. It simply does nothing from the steering wheel. I bought brand new buttons as well to make sure it wasn't the buttons.

So I may actually be unsure if I have the steering wheel controls from the head unit wired right. In the photo below, the top left tells how to wire the black, red and pink wire. I have that done correctly.

However, in the picture below, the white "KEY(Steering wheel controls)" wire I have connected to the pink wire in pin A1 as well. Is this incorrect? If so, what is the proper wire to connect that too from the car harness?
