The 426 is a upgrade of the 2009-2010 to a 2011 is what I was told , but now I am confused as is others. It is entered as a 2009 - 426. We started it up today and everything seems good except the windows stoped working . I guess they are not 426 compatible. Now we have to get them working. Will they not work with 16 volt? I converted it from 12v to 16v and they stopped working.

The 426 sounds real good.
