   After lots of time studying the FSM, digging around the Dak and way
to many trail and errors. Finally able to get the Viper fan to shut off
when the Dak is moving at a speed that a fan is not needed. Now with the
A/C on, the Viper fan will automatically shut off when the Dakota
reaches appox 30mph. When speed drops to appox 15mph the fan will
automatically turn back on. In this configuration controller will turn
the fan on during heavy acceleration and or when the radiator mounted
temperature probe call for cooling. The three other setting can still be
used.

1 Manual -- OFF
2 Manual -- ON
3 Auto ON -- A/C off, controlled by engine temperature
4 Auto ON -- A/C on, controlled by truck speed. {controlled by engine
temperature, will overrides truck speed shut off feature}

Prior to this new additional control, the viper fan would run
continually when the A/C was on and "Auto ON" mode was selected.
