Electric rad fan control

My solution for my '82 258 c.i. Spirit GT was a simple manual toggle switch 
on the dash.  Depending on where you drive, the fan is not necessary as long 
as the car is moving in summer - the "radiator"  and the thermostat/water 
pump in the cooling system will handle the extraction of heat from the 
engine.  It is a fairly large block, so a lot of heat is dumped directly to 
the air and metal around the block by radiation and convection.  I found 
that the fan was most beneficial to cool down the engine in parking lots in 
summer - the only time I ever switched it on. An engine coolant temperature 
guage is a good and inexpensive augmentation.  Power gain is probably 15 HP 
with the electric fan, and you give away a lot of vibration by chucking the 
steel windmill - really noticeable off the line.
