See http://fordfuelinjection.com/files/A9L_E-Fan_How-to.pdf for the how to do an electric fan & use the computer's built in temp sensor.
Oh no, you got a Proform, aka Black Tragic. I used one for about 2 months, before selling it and getting a 3.8 taurus for 1/4 that price and it works 100000% better then that thing. The controller is built into the fan itself, and if should have come with the wiring kit.. if not, contact the seller.
