I wired in an under-hood switch in my setup as well. This is optional, but I thought it would be good to be able to pop the hood and turn on the fan at the drag strip, or just in case I started to overheat. It's really simple.

The fan controller has a green wire that can be wired to the A/C compressor so that the fan switches on when A/C is on. Since I removed my A/C, I used a switch to control power to the green wire. Connect the green wire from the fan controller to your switch, and connect an ignition-powered wire (preferably the same one you wired the controller to) to the other terminal of the switch.

After wiring the fan in this manner, I read about another method for running a two-speed or dual fan.

Wire the low speed to a relay and temp probe. Then wire the second speed (or second fan) to the AC condenser fan plug. The condenser fan is set (from the factory) to come on at water temps above 212°F. Therefore, it would be possible to wire it in such a way that the fan was on low at the controller's set temperature, and then kicked to high when the water temperature reached 212°F.

Next time I wire up a fan, I will most likely try this method.
