The Pedal will say how much to open & being 6 wire will monitor itself for errors. Any errors will result in limp home mode.
Ive just guessed at this & await the info to check.
I know the belt and braces approach is to use a 6 wire setup so that you have 2 self sufficient pots on the pedal, but for what it's worth, i've run the 4 wire setup pedals (common reference voltage and signal ground) successfully for a good few years now without problem.
With correctly configured redundancy strategies there is no reason that they should be dismissed
Might open up a few more options for you
