Got this info from a site that deals with ford scanning and diagnostics..

Here's what they state are CAN based vehicles from Ford so far. Just to help people not get confused with what they have.
Models 2003 and up
Ford Focus with a 2.3L engine only
Ford F150, except F150 Heritage
Ford Excursion (with 6.0L diesel only)
Ford Explorer
Ford Taurus
Ford Thunderbird
Lincoln LS
Mercury Mountaineer
Mercury Sable
The percentage of ford vehicles that will be using CAN moving forward are:
50% in 2004
85% in 2005
90% in 2006
100% in 2007
If you know of any else, please post up!
