Electric fan install help.

I did talk to Tony before purchasing, I'm a complete novice with this, but what I get is from talking to him is that the fans will ramp up to low and then if needed go to high to prevent a high spike of off to hammering the voltage to high, which would be nice in our fragile systems. Also it looks like the harness will just need the fan connections changed, but I'm sure thats to good to be true so I may end up using the Cougar harness anyway. Two big things for me is, one- weatherproof, this runs off the alternator so no wiring going to the pass area just to come back to the front of the car, and two- everything included, no shopping for extra parts, relays,wiring, fuses. I will definately keep updating to let you guys know what I find, I do know since I found the link here someone else is running it. Anyway it should be interesting, maybe it's a great solution, maybe not, but we shall see.
