Or you can hook up a painless wiring kit like I did. Its real simple. I just make a pipe that tapped into the radiator hose, but it in 2 pieces and clamped the other ends. Ran the sensor in there. Power to a relay, ground, ignition, and thats it. Turns on at 190 and off at 170. Its not good to leave your fans on all the time becuase they will live a shorter life. FAL fans arnt cheep. You can see in the pic where I put the sensor.
