If our trucks are setup right you really don't need a electric fan at all inless you pull a lot or sit in a lot of traffic. The more air flow you get through the radiator the better cooling you will have. This is why I installed the cover between the condensor and radiator support to help force more air threw. I can't really say if it does or doesn't help but my electric fan is under there too!

It also forces the air threw my home made cold air box also!

Works great you come off the batt for power.

I have always heard that the old coil wire is less than 12V... does it matter if it's only running a relay?

If he is using the wire with a HEI then it's not got the resister in it anymore or his truck wouldn't crank. I did the same thing just cut the old resister wire out of the harness and used it for the HEI. At least mine wouldn't at first.
