The LT1 is a popular small-block engine made by General Motors. First appearing in 1992, it was the powerplant of choice for various Chevrolets, Buicks and Pontiacs throughout the 1990s. The LT1s wiring uses a single harness, consisting mainly of simple push-on connectors. If you stay organized and plan correctly, a complete LT1 rewire is not a difficult project.
