Vintage air question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 5.3 gen iii and I am trying to install it. I want to use the pcm to run the a/c system but it is a stand alone system from vintage air. My gen iii harness says I have a lime green wire that is for the a/c clutch and a red that is a/c request. Where do I hook them up to? I have found that I have a Sanden sd7 compressor and it will have to be tuned to fixed in hptuner. Just really don't want to mess up my new system. Any help would be great. Thanks
