Vaders are different from regular or sport seats in how the cushions come off... (My bowden cable on the passenger side is broken, I just haven't gotten around to fixing it)
You will need to remove the seat to access the lower cable connection, and the upper cushion is not held on with screws, but a lip attached to the leather that tucks back into a groove or lip on the back
There are some close up pics in this thread with the leather off that may help
