Description

Nelson Performance manufactures every harness we sell in our shop in San Antonio, Texas USA.  Texans know heat and we know the amount of draw/load that heat puts on your engine!  Remove the stock mechanical clutch fan assembly and replace it with an electric fan assembly.  This conversion frees up horsepower and leads to cooler engine and ac temps!

Don’t be fooled by inexpensive knock offs!

All our electric fan harnesses are made in the USA.

We use high-temp resistant TXL wiring that is rated at 260 degrees.

NP harnesses come with (3) 50 amp high-quality relays with resistors.

Our relay blocks are sealed with TPA retainers, meaning they are water/corrosion resistant.

All  terminals are crimped using OEM (Original Equipment Manufacturer-General Motors) tooling.

All eyelet terminals are quality crimped and soldered.

We use 8 gauge TXL power wires that are rated at 260 degrees.

We now use a 60 amp J-case fuse with a water sealed case.

This e-fan harness is for 2003 to 2007 Classic Body Style GM truck/suvs that have a mechanical clutch fan and are wanting to convert to an ’05+ e-fan assembly using the wider 34″ radiator.  Note:  The majority of the 1/2ton trucks had the narrower 28″ wide radiator.

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.
