Well...you can wire a switch...one side to battery through a 40 amp fuse, other side to the (+) wire for the fan motor. Make sure to use heavy enough wire and switch to carry 40 amps. And shut it off when you kill the engine, 40 amps will drain your battery pretty quickly.
Or..you can wire one end of the switch to ground, the other end to the dark blue/pink stripe wire that operates the fan relay. You'll find it easiest to access at the PCM connector, if my book is right it's at PCM pin 31 for your year.
