PRODUCT DETAILS

Nelson Performance's electric fan conversion harness works with all 1999-2006 GM trucks and SUVs. It allows the replacement of the clutch fan with a more efficient electric fan. The harness is plug-n-play for the LS1/LT1 style Camaro e-fans or the 2005 OEM truck e-fans, or is even available with universal pigtail ends if you're running an aftermarket or universal fan.

 

NOTE: 1999-2002 style with LS1 fan connections pictured.

Harnesses are made with high-quality TXL rated wire and all terminals are OEM crimped and/or soldered to avoid corrosion and contact problems.

 

Each harness is covered in wire loom and made with OEM weather-pack connectors. The relays are rated at 40 amps and are sealed and water tight; this means no corrosion on the terminals.

 

The 1999-2002 variation of the harness has a single PCM trigger wire and a secondary trigger wire that taps in to the AC compressor clutch signal. This orientation allows a single fan to run on high when the AC is engaged and runs both fans on high when the engine temperature threshold is met.

 

The 2003-2004 variation of the harness has two PCM trigger wires and allows complete control of the electric fans by the PCM and the 2003 and later trucks.


*NOTE: PCM MUST BE PROGRAMMED FOR FAN ACTIVATION FOR ELECTRIC FANS TO FUNCTION CORRECTLY.
