It sounds like the connections of your # 5504 that need to be made under the hood of the vehicle have not been made. There are two wires, both Red/Black with eyelets on the end. One wire is located between the fuse box and the driver side fender, the other wire is located under the brake master cylinder.

Each wire has a different sized eyelet on the them and will connect to the studs at the front of the fuse box. You will need an M6 nut, part # 185916 and an M8 nut, part # 185917, to attach wires to studs.

I have linked an FAQ on brake controller installation on the GM Full-Size trucks that illustrates the under hood connections you need to make.
