Hi, I'm new and I've been searching around. I'm trying to get some help with getting the Steering Wheel controls to work with this 2012 Rav4. It's got a Pioneer AVH400-NEX headunit in it that was installed before the purchase of this car. So when I bought the Axxess adapter, and the plug and play adapter, but once we got behind the dash I do not see a 24 pin connector to plug into, a bunch of cut wires, I found a small 22 pin connector which looks similar to what the Axxess adapter instructions mentions, but the pin numbers don't match up. I was wondering if anyone has pictures, wire colors, or wiring diagrams of what I should be looking for in order to install this?
