Way to make the fan run all the time?

Well I am getting ready to go to the track tmrw night and I am curious about making the fan run all the time to cool the motor down between passes..when I had my last car (a 92 toyota celica gt ..ya I know an ex ricer) I could unplug the temp sensor from the radiator and the fan would run anytime the switch was on since the senson wasn't reporting properly..I know I shouldn't really worry about it but my car runs MUCH better at half way or so on the temp hand than it does at the normal wich stays w/the hand between M & A where it says normal on the gauge (quater past half). If there is a simple way to do this I would appreciate it and I will see what type of difference it makes...thanks guys
 
Someone mus know a better solution..I mean its going to cost me 20 bucks jsut to run on an 1/8th mile track wich is ****ty if you ask me so I don't want to spend all my time waiting on the car to cool between runs ...anyone?
