    I've been working on a fan harness for you guys and wanted to let you know what i've come up with.
    Basically it's a copy of the camaro fans, but with some variations.

    The kit consists of 3 relays, and three inputs.
    It works like this.

    The fans will come on low when commanded by the PCM based on temp, the fans will go high when the a/c is turned on, then, when you're at the track, there is an option to have a toggle switch to turn them on high to cool down.
    I'm also going to make the simple/basic harness, two relays and two inputs, when the pcm commands the fans on, it will go high and when the a/c comes on they will go high.

    I'm waiting on just a couple small parts and i'll have about 10 of them done, after the GP i'll be making more.

    Anyone interested?

    I haven't thought much about the price, but they'll be priced very reasonble.

    Yes, high only when the a/c is on, or if you manually turn them on high. the ls1 fans will cool an engine just fine on low speed , hell, just one of my fans will cool my engine.


    thanks,
