You can hook it up either via a manual switch which creates two options in itself:
1) a single high amp switch which manually activates the fan at whichever speed you have wired up.
2) two switches or a single three postion switch which allows you to select off, slow speed, or high speed.

or: you can attach a thermostatically activated switch to the circuit automatically triggering the fan if you have a habit of forgetting to throw the switch on when you start the car.

The SN 95 pulls a lot of amps so I recommend a 130 amp alternator and no underdrives. But it is a very nice and extremely quiet.

I got all of the parts from NAPA, the hardest thing to find was a high amp switch b/c I chose to not wire in a step-down for simplicity.

I got the fan from Racer Walsh here in Jacksonville, $200, and I got the fan plug from a junkyard for 2 bucks and used it to make the wiring look nice. Other than that, it's just wire, a switch, and a in-line fuse. I wired only the high speed connection so it pulls some amps at idle but I have a Powermaster, so it's cool.
