A/C harness install - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I bought and installed a new American Autoworks a/c harness yesterday. I worked backwards removing the old and installing the new, to make sure everything was correct. All wires and plugs accounted for, and connected. My issue arose once I got to the fuse box. The original harness had one connector which plugged into the cig terminal. The replacement harness has two - one orange and one gray.

I believe the orange goes to the cig. Just not sure about the gray. Any ideas?
