The new  fans are three-speed units, with the speed controlled from within 
the fan  itself.   They have four wires--a ground, and three individual 
power  
wires, each of which controls a different speed.   You get to  choose which 
two of the three speeds you want (since your stock switch  will only 
support 
two speeds, and 'off'.   Once you've done  that, it then becomes a very 
straightforward matter to wire the fan to the  switch.

Actually with a little creative wiring using relays and the unused  switch 
on L cars, you can get it to work as a 3 speed. It's an interesting logic  
problem but it actually works well and looks absolutely stock.
