I am currently building my car and as yet do not have a fan in it. I figured since there's nothing I might as well add an electric fan now. I was just wondering how to go about putting some of those contour fans in. I want it to run off of the temperature like stock. I'm not trying to put it on a switch and constantly keep an eye on the temp... Is there any instructions with pictures maybe? Thanks.

for dual contour fans, flex a lite #33054 temp controller, then wire both fans together using 10g wiring (10 gauge wire for everything except for 12v switched 12-14 gauge is fine)to the controller, use a 40amp inline fuse or self-resetting circuit breaker for the 12v constant to the controller, 12v switch source was the coolant overflow sensor, and then run the temp probe near the upper rad outlet set your desired temp on the controller then done, good thing about this controller is it has a soft start so your amps wont spike when both fans kick on, they will start at 60% power and eventually spin at 100% when the temps go over your temp setting, this is what i just did last month and it stays at about 190*-195*, i used a cheapy overflow bottle from kragens and tucked it in the drivers fenderwell.

i wired my temp controller to the battery. if you dont want the fans on after you turn the car off, wire the temp controller circuit to the low coolant sensor

And this is what you wired on your car? What is the last item on the list(80 amp maxi-fuse)?

That would be the fuse for the main power wire for the fan. Thats why i prefer the contour fans because they draw 38 amps, compared to the mark 8 fan that draws 80 amps, moves almost as much air and covers more area of the radiator.
