Electric Fan Installation with Flex-A-Lite on F150

Using the Flex-a-lite 270 Electric fan for the 97-2003 F150! Mine is a 2002! I was able to feel a perceived increase in power and gas mileage!! It is probably the most uncontested perceived increase in power and mpg.

NOTE: If you have an aftermarket radiator like I did be prepared to make modifications or buy a new radiator!! I show you how to make the modifications!
ANOTHER NOTE:
The fan will run while truck is off! But that is because you probably connected to the negative on the AC unit. I did the same thing need to move it to the positive or vice versa I forget(sorry man dont feel like going under truck right now to look). I describe this at 11:46 . If this is not your case--make sure that you adjusted the temp control I set mine to a little past middle as the fan will continue to run even after the truck is off and this is normal in this set up. Even if you set temp higher the fan will run if its high temp but wont run for long. The only other way is to tie in the thin red wire into a positive line that only turns on only when key is turned on. I didnt do this cause I was ok with the fan running a bit after I shut engine off. I would love to hear the rest of your story...please post your results
