Denny Ken is correct about the switch for offroaders. i think the GM fan would hold up but, better safe than sorry and only thing You have to do is remember to turn it off into water and back on. Very cheap insurance for sure.
Go to eadperformance.com and look up
OEM Electric GM Truck Fan.
then go to Nelson Performance and buy the wiring harness He has already built for this purpose. Has relays etc. and can be programmed to turn off and on if You have tuning software or know someone who does. Not handheld programers but, software like HP Tuning.
You will have to cut tranny cooling lines so fan will fit. Cut lines for the room needed and then splice rubber hose between the cut out sections that will be removed to fit fan in. You will have to do this for both lines.
Wiring harness comes with insrtuctions on how to hook it up and the electric fan will not bolt into H2 holes. Line up dual fans and mark where You will need to drill fan shroud. The holes that old fan used will work to bolt on.
Use a rubber washer between shroud and frame and shroud and bolt head. gives some cushion against vibration. Do not over tighten or You bust shroud. I did not take the time but if You can find a metal insert to go in shroud hole so that bolt will pull up snug on spacer it would prevent over tightening and cracking shroud.

Taz,
I need help.
I need to know who you spoke with at Nelson Performance about this wiring harness and more important I need a part number.
The service manager at my dealership has his parts people trying to track down this info and they are coming up empty.
As a GM/Hummer Dealer they can get the fans for the HD 2500 but they have no idea what your talking about with regards to this harness from Nelson Performance. I've even called Nelson and spoke someone, and sorry I didn't get his name but he and he had no idea what I was talking about.
I'd like to get positive info about this asap so that I can make the Oct Moab run that some of the folks here on the board are going to.
Thanks in advance for any help.
