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!

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 proof.

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 1999 to 2002 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.
