Here's a link to Summit Racing where I got mine for ~$370 plus the $17 cab switch assembly. Like I said this is not a great "bang for the buck" mod unless you want it for other technical reasons. <img src="/forums/images/graemlins/rolleyes.gif" alt="" />

The fan was installed by a friend who runs an automotive serveice company and seemed fairly straight-forward using the included instructions. My only exception was we ran the controller wiring inside the fan-shroud using wire ties looped around the wire on the inside putting the large catchblock on the outside against the molded holes. This gave it a fairly clean look and should keep the controller and wiring out of sight and above most of the heat. Here are a couple of PICs:

Clicky 2

Oh and you'll need some washers to use on the old studs left vacant by the removal of the OEM clutch fan. These studs have a non-threaded center section that won't allow the nuts to be tightened down without running out of thread. Use the same type and number on each stud or you'll be out of balance.

For more in-depth discussion, try searching via Yahoo or Google as I found 2 or 3 write-ups when I had the same questions. They were specific to Tacomas but seemed very similar. <img src="/forums/images/graemlins/cheers.gif" alt="" /> Good Luck. Brew
