This e-fan harness is for the GMT800 1/2 ton GM truck/suv electric fan assembly.
– Note: GMT800 simply means 1999-2006/7 GM truck/suv vehicles.
– Note GMT900 simply means 2008+ and newer GM truck/suv vehicles.
This e-fan harness is for GM truck/suv that have a mechanical clutch fan and are wanting to convert to an ’05+ e-fan assembly using the wider 34″ radiator.
The majority of GMT800 vehicles had the narrower 28″ wide radiator. This harness is for the GM 1/2 ton trucks that are equipped with the wider 34″ radiator.
Some 1/2 ton trucks are equipped with the wider 34″ radiator but still have the factory mechanical clutch fan, so there is no need to change the radiator.
In order to use this harness your vehicle must be equipped with the wider 34″ radiator or you must purchase the wide 34″ radiator from your local auto parts store.
To determine if you have selected the correct harness, take some time to view the pictures and identify the e-fan connector type that matches your e-fan assembly.
