This e-fan harness works with 99-2006(07) GM Truck/SUV, using the GM Truck/SUV OEM e-fan assembly.
It allows the use of electric fans on a full-size GM Truck that was originally equipped with a clutch fan.
Your vehicle must be equipped with the larger radiator. The GM OEM e-fan fits the larger 34" radiator.
If you're unsure, compare your truck's radiator to another truck that was equipped with OEM e-fans.
Our e-fan harness is PnP for GM Trucks 99-06(07) GMT800.
PCM activation is required for correct functionality.
