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.

Here's a link to the FORD service manual fan wiring diagram PDF...

So I did this simple mod to it...




It looks like this in my car...

Nice looks good. Did you make your cup houlder mount?
Yes I made the aluminum mounting plate but not the trim ring. I originally made one for the line lock controls, but had to make another one when I added this switch.

nice so does it still have its normal operations just you can turn it on high when the car isnt on ?
Yes the fan works as it normally does and I keep the switch off on the street, but if I need to ativate the fan at the track or Dyno shop, I just hit the button and the ingnition key does not need to be on.

next put an electric water pump on also so you can run that at the same time after a run to cool down all the coolant instead of whats just in the radiator

well there you go, those are my future plans once i get more stuff down before dropping 350 on an elec wp. beats having to pack a high velocity fan to go to the track. My fans are already hooked up to a switch but kinda pointless without the wp

Not entirely pointless, some of my friends say they get a 50-75 degree drop in 15-20 minutes with just the fan switch.
