e-fan wiring?
Alright I dont want to spend $500+ for an electric fan kit specific for my truck. I have 2 single perma cool 14" fans that push out 2950 cfm each. I was wondering if I get the wiring harness if I have to hook it up a certain way to have one fan kick on then have the other one kick on when it needs to and then have them both kick on when the a/c is turned on?

The only reason to have double fans or have it kick up is for temps. The main question is how are you going to turn the fans on and what is your set points. The current engine fan only runs at one speed. You would want the fan to come on with the a/c so you could tap into the ac clutch. You would need some sort of temp switch so when the engine temp reaches temp, the fan comes on. Normally, there's 2 set points so when the temps get high, both fans or high speed come on. Low speed or 1 fan is normal for most operations.

The wiring harness has a thermostat and says i need an extra relay to run the other fan. Im just guesssing but i would think I would need another thermostat for the other one. So other than that if i tap in to the a/c clutch I should be good?
