It dosn't have to that complicated (searching for a ecm output and table ).
Look in a auto parts catalog for a water temp switch used for a hot light.
Many have a small screw covered by paint or sealer. Most of the older Ford
sensors have a threaded stud with a flat on one side.

Clean off the paint, then turn the screw two turns clockwise. Most engines
have extra pluged holes in the intake or cylinder heads. Connect the switch to
the relay for the second fan.  Run the engine and adjust the screw to the temp
you desire.

Simple, easy and cheap.
