You COULD install a switch BUT you run the risk of forgetting!! There is a fan cycling switch/relay you can replace.

I installed an electric fan in my foxbody. Its controlled by an adjustable temperature switch (its comes on at a certain temperature even of the switch is off) and a 25 amp switch. I also wired in an indicator light to ensure I knew it was running or not.
