After seeing several others with this mod at the track last week I decided to install a manual switch for the hi speed cooling fan, to help cool the motor down between runs, it is also handy for cooling between dyno runs.
I mounted a lighted rocker switch in my front cup holder next to my line lock controls. A ver simple wotrhwhile modification for those who drag race. It only took about an hour or so to do. All you need is a switch, about 12' of 16 or 18 ga wire, an inline fuse holder, and a few wire connectors, I got all of it at Radio Shack.

So I did this simple mod to it...
It looks like this in my car...
