This harness works with '05+ Silverado, OEM style e-fan assemblies for 99-06 trucks/suv.
Allows the use of electric fans on a full-size GM Truck that was originally equipped with a clutch fan.
Our efan harness is PnP for GM Trucks 99-06 GMT800.
PCM activation is required for correct functionality.
It has come to our attention that a manufacturer has duplicated the GM OEM e-fan assembly incorrectly!
One set in particular is made by GPD. PN 2811689
Concern - efans turn backwards
If you purchased this e-fan assembly then you must notify us before we ship your harness. This is not a mistake on our part, the manufacturer has built these incorrectly. They are designed to be a replacement for the 05+ and newer GM trucks but when installed the e-fans turn backwards and push air forward.
