Dear 12Oz,
Actually the question about the wiring diagram is a kind of a 'red herring'.
Because I know that mistake was corrected in the April 2006 release of the "1996-2002 Service Information, FCS-13801-LEGACY5" DVD. My intent is to locate someone who knows the answer to the second question:
Where, are the SCP/J1850 PWM terminating resistors located in a 2001 Windstar?
