Patches and discussion for Ensoniq VFX family

I am having the classic coil board conector problem, calibration 
problems, random playing, dead keys which improve or change 
by racking and bending the removed keyboard (error #144)
however I do not have the 12 pin connector I have the 2 rows of 
10 pins (20 pin connector) and the repair bulletins all describe 
the repair for 12 pins and say send the 20 pin connector 
keyboards basck to the factory.  Can I jump these just like the 12 
pin and if so what is the layout of the connections (out to out and 
in to in or out to in)?  If the jump is not the fix any ideas where to 
look for a solution?
