Thanks so just to clarify with the 02 ecm and proper configuration the fans will work with the a/c on and off switch and coolant temperature will also act as an input for their controll

Oh and just secure the other wire that was removed out of the way, when you say use the oem harness is the two pin aftermarket harness acceptable?

Efan with oem parts

I’m wanting to go to the Efan setup using oem parts for my 04 Silverado..any advice you can send my way such as a parts list would be greatly appreciated.
