Default adding fan control through ECU Gen 3 5.3's
I'm starting to look for a good donor vehicle for my LS swap. I suspect I will end up with a Tahoe or Suburban and it will most likely be a 5.3. I want electric cooling fans and not all of the Gen 3 trucks had this. I don't even know when it started. I just know my 01 Sierra didn't have it and my 06 Tahoe does. If I end up with a water pump driven fan donor vehicle, can I easily wire in factory fans and reflash the ECU to control them? If not, any one know what year the electric fans started or have an alternative suggestion for having electrical fans? I would really like to stay with factory GM fans. They work great, are easy to find, and inexpensive.

Thanks
