Default E-fan install questions

I have never messed with e-fans before so take that into consideration. Is there a wiring diagram that I can follow? I herd about a temp sensor or something that you can get, does is sensor know how hot or cold the engine is and regulates the fan off and on so I don't have to mess with them? Where can you get the temp sensor and wiring for the fans? Also I have the stock stereo system so I'm not that worried about my voltage, although will my voltage drop if I have the ASP crank and alt. pulleys? A little lower voltage won't hurt anything will it?

you can get the vsc from flexi-lite. it will come with the sensor and directions on how to hook them up. im think the pulleys may cause charging problems but i not for sure. i cratered my altenator and battery not long after the install, but i also was pushing a stereo system too.

If you have a ASP and electric fans.......I suggest a 180-200 amp alt. I had to get one anyway......

I used an Imperial brand fan controller for my e-fans, got it at Kragans auto parts (Shucks & Checker, same stores). It was about $35 and has all the info. you need to install it, uses a temp probe with an adjustable thermostat to control the fans. It can control two fans but for some reason they only fused one lead, I bought another inline fuse for the other lead so both fans are fused. Other than that, it's simple and easy to install.
