LT1 fans
 

I have a Nelson Performance LT1 fan wiring harness (new) and LT1 fans (used) for the GM trucks to convert from the clutch fan to electric fans. I never got around to installing it on my 2001 Silverado and the truck has been sold. I think it should be good for 1999-2004 GM full size trucks. $140 for the harness and fans.

Im interested... This a plug and play kit once the stock fan is removed?

You need to get the computer tuned to turn on the fan from what i researched. And also you need the larger (30" or something) radiator for the fans. Dont quote me cause I havent done it myself.

You would need to tune it to turn on the fans, I think you can do that with the Diablosport or other tuners. You need to insert one wire into the PCM pin and the instructions show you how to do that. You would need to come up with your own mounting brackets to install the fans and shroud. I don't think you need the bigger radiator. The harness plugs right into the LT1 fans.

Updated the price and if anyone is interested in the fans alone I'll sell them seperately for $60.

Harness is sold so the fans are still available.
