I put one of those babies in my F150 (2002) and they can move a lot of air, much more than the Taurus fan. The other member mentioned 75 amp relays and I would say that is good advice....I have used a fluke meter when the high speed comes on and it spiked at 88 amps for a split second.

Anyone ever run these babies?? I here good and bad about the Global COPS you see on ebay, and what Ford is asking for oem's is down right criminal.
