Just brought this thing home, and I knew as soon as we hooked up the rear lights that I only had one brake light. Before I start chasing wires, could this be something crazy? I don't know a whole lot about these things yet, it's a 97 Cab/Chassis 4x4, and I had to install rear lights because I didn't get it with a bed. If I just need to chase wires, then that's what I'll do. If it's something else, then I dunno what I'm going to do. Thanks!
