Which cables are for the steering wheel controls in my van? I installed an aftermarket radio and it came with a key1 and key2 for steering wheel I believe. The main harness also has a steering wheel wire in it.

Hello, I'm Danny.

Before we get started I need to know what stereo system your van is equipped with. I've attached a picture below of the options. Let us know and we'll be happy to help. Hope this helps and thanks for using 2CarPros.

Hello again.

Here is the wiring diagram you requested for vans radio without navigation and without rear seat audio. I've attached the picture below and cut into 2 pieces so you can view larger. I've circled in red the 3 wires which are in color for the steering wheel controls. Hope this helps and thanks for using 2CarPros.

In the second diagram outlined in red, the blue and light green wires are for the steering wheel controls. Can I use the wires in my aftermarket radio with key1 and key2 to connect to the SW1 and SW2 blue and light green wires?

Hello again.

The wiring diagram remains the same for wire colors for without navigation and having rear audio. Yes, use those wires for key 1 and 2. I've attached a picture again below. Hope this helps and thanks again for using 2CarPros.
