Default efan mod to my 98 Silverado

Anyone have any links or anything to do this? I figure i will have to hook up HP tuners to get the fans to turn on lower, but just tryign to figure some stuff out.

It has 6" lift on 305/70/16 wheels, so making it extremely fats is a bit out of the question, but i would love to give it some *****.

So any help would be appreciative

You need to wire the fan with a relay and the pcm will provide a ground on pin #9 connector #4. The wire is not in the harness at the pcm it needs to be added. I just used a single fan on the one I did. Then with hp tuners you will have to set up the fan temps.
