Are you sure it is a 9-pin connector, or might it be a 10-pin? I pulled up the wiring diagram for the transmission in a 2002 Taurus and it shows a 10-pin D-connector, and pin 3 is for the TCC, pin 6 is Shift Solenoid B. Pin 4 is not used, so there are only 9 wires going to the connector, but there are 10 positions in the connector.
If you'd like me to send you a PDF attachment of connector C199, send me a private message with your e-mail address and request.
I don't find anything in the service manual regarding specs for the TFT sensor. I find it mentioned as being an integral part of the transmission control body, but nothing on what resistance/voltage drop to expect for certain temperatures.
