anyone have any details on this one? 01-02 PCM. I know it is possible to get a signal from the PCM to enable the fans given the command, like a vette or camaro. What is the location? and what are the gains in HP? 10RWHP on a 5.3? Does the camaro fan setup work? What are you guys using for fans?

Most use the Flex-a-Lite 282's. The problem with this is you have to have the bigger radiator.

I think the Camaro fans will fit on the smaller radiator, but I'm not sure.

I read somewhere that you can tap intthe PCM and use a relay to turn the fans on and off using the PCM, but I don't remember what number pin it was. Try looking around a little bit and see if you can find it.

I just put my fans on mine tonite, along with the bigger radiator. I like the sound of them MUCH better than the stocker. I'm not sure of any gains though.
