So I did an E-fan mod last night...
I pulled a fan fron a Ford Taurus SHO, fabbed some mounting brackets and bought a wiring kit from PepBoys. The kit has a 75amp relay, fuse, and a toggle switch. It did come with a radiator probe, but it broke off too early, so wouldn't penetrate all the way. Right now it's wired up like this:
Fan power----fuse----relay
Fan ground---- chassis ground
Relay power----battery +
Relay ground----chassis ground
Relay supply----fuse----fan power
Relay switch (brown)----toggle switch
Relay switch (green)----not used
Relay switch (blue)----not used (for dual fans)
Toggle switch 1----12v ignition on source ( stereo power )
Toggle switch 2----Relay switch (brown)
Toggle switch 3----Chassis ground
It definitely works... but i was wondering if anyone sees any issues I may run into??? I'm going to put up pictures later on today.

i have mine wired on the low speed with a variable temp sensor so it turns on when the truck hits a certain temp (hard wired with a fuse inline so it continues to pull heat out of the radiator after the truck is off). I also have it connected through a relay to the high side of the fan for really hot days when towing and the low side cant keep up (i.e. towing a 10k lb trailer up 7,000 ft mountains in utah in 110 degrees). I flip a switch in the cab and it overrides the low speed, turning on the high speed. when i flip the switch off, its back to being controlled by the variable thermostat.
