To install a brake controller like the # 5504 that you referenced you only need to connect it to 4 wires. If you find more wires on your vehicle than would be needed to install the controller you wouldn't need to do anything with them. I attached a chart that shows how a brake controller gets wired to a vehicle.

If your 2003 Chevy Silverado has a factory 7-way like what you mentioned you would only need the install harness part # 3015-P to install the controller. I attached a video that shows how this harness is used to install a controller.
