GM HD electric cooling fans

Found a GM HD electric cooling fan at the local junk yard its a pull off from a 08 or so hummer H2 its a dual fan set up, would this bolt on to my 04 6.0 denali radaitor? Also does nelson performance make a OE type harness to operate this fan with my PCM?

Not sure on the fans, but yes nelson makes a harness to run fans. You will also need a tune to make the fans work

Your Yukon should have the larger 34" radiator, therefore the fans will indeed bolt right up. I am fairly sure Nelson does make a harness, but concensus around here seems to be that blackbear harness is of a little higher quality. Either way you will want the "2 pin" harness which allows full PCM control of the fans.
