There are differences. The 6 pin brown connector for the passenger headset is the same. The second 6 pin connector that is shown does not exist on the Valkyrie. The Valkyrie does have a pair of pins for PTT but not the 6-pin connector shown. I don't have a wiring schematic for the Wing so I don't know if they could be made to pair up somehow.
Edit: If I had to guess then the second 6-pin connector might be a combination of PTT and volume control functions. I know that the brown 6-pin connector that is on the Valkyrie is just R & L headset speakers and microphone connections.
