Actually, this fuse block has provisions for the radio, horn, wipers, heater/AC, etc. I've already wired all those in. It also has provisions for turn signals, emergency flashers, an electric fan (if equipped), coil, ignition switch, light switch, stop switch, dome light, etc. All have been already wired in. I guess I'm only concerned about 2 things, how the gauges are powered, and how to wire in the stock ammeter.
