Electric fan wiring and temp question

I am converting my mechanical clutch fan to an electric unit I bought from LCE. The question I have is I tapped into my radio 12v on my fuse box when I wired my fogs. Can I use that same connection for the 12v fan connection? Or will it overload it. I am thinking it just is signaling it to turn on and not powering so it should be okay...right?

Other question is once it is installed it says to calibrate it to turn on at a certan temp. Anyone have suggestions on how to do this and/what temp it should it start running at?

 

There is a direct battery connection but for the fan to turn on only when the car is on it requires a 12v ignition hook up. Still use the fuse box in engine compartment?

 

Yes this is the diagram. The main question is the 12v thermostatic wire. I have my 12 v tapped into from wiring aftermarket fogs on the stereo in the cab. Can I use this? Or is there a better option in the engine compartment fuse box?

Also where is the positive wire for the ac compressor for the green wire hook up?

 

Is the compressor the pulley on the front of the engine, right top with a canaster on top of it? I have the 2.7

 

Good info, saving this one for later!

 

Perfect! Thanks for all the help on this!
