Is the parking brake light supposed to be on, on the BOSS panel? I ask because I found a dead plug, connected to the harness under the seat, sitting on top of the chaincase, right next to the brake. It wasn't hooked up to anything, but my parking brake light doesn't come on when I engage the brake. It would be the right length to connect to something near the brake. One of the wires are green& red. Any ideas?
