05+ E fans on my 04 Denali

[Yukon04]

Since it has been so cold here I went ahead and removed my cluch fan just to see the performance and MPG gains from the future E fan swap and I am impressed so far. I already have the factory E fan set from a 05 truck, I need to know how has the best wiring harness and how do I go about getting my tune done?

Contact BlackBear performance or Nelson to obtain a wiring harness and tune. You can make your own harness if you want and search the site for the schematic. Its worth the swap.
