how should i do it. manualy? make my own switch . if so whats the easiest way

 

easiest way is to but a switch and run the fan to it then run a power wire to the switch but you have to remember to turn on the switch on...........or you could buy a relay kit around 60 bucks from summit or i belive you could have a chip burned for that too.
My suggestion is to buy a kit because if your like me you'll forget to turn the fan on, it up to you though dude 1 last point the temp gauge in my car went out so i got a digital temp gauge from summit for 30 sum bucks so i know what temp i'm at.....just some cheap insurance....good luck

 

i would think the easiest, cheap, safe way is to buy a lower temp switch. all you got to do is replace your old on with that one and it makes the fan turn on cooler. look at summit for those!! Hypertech and Jet performace makes them.
