Hi,
sorry for the late reply.
For the connection of steering wheel control problem,the picture is just allowed to refer,it is not your real connector.In your car,there is a connector containing the steering SW1,steering SW2 and SW Ground wire,you just need to manually connect them to the w+1 wire,w+2 wire and black wire of the ISO cable of our unit.If you want to connect them easily,you can buy an adapter.Here is the link.

Sorry again,i don't understand your question well.If you still have problem, could you mind provide a video to show us your question?
Regard.
