Toby,
The ones you say that one of them is attached to the aileron applies to the DVa version; it's aileron rigging was different from the DV which had the control cables internal to the wing. Take a look at the Plans Booklet Rigging diagrams for the DV and DVa on the Wingnut Wings Site as Bo has indicated and the difference will be easily apparent.
Hope this helps.
Cheers,
Lance
