LS-series ignition coils are interchangeable. As an example, you can swap a 2002 Corvette ignition coil bracket assembly (ignition coils, mounting bracket, and coil harness) with a 2008 Corvette ignition coil bracket assembly. General Motors has designed each ignition coil pack harness to be universal to any LS-series engine wire harness. General Motors has used a variety of ignition coils with LS-series engines. GM# 12558948 ignition coil (bottom left) is only used with the LS1 and LS6 engine in the Camaro, Firebird, Corvette, and Cadillac CTS-V. GM# 12573190 ignition coil (middle left) and GM# 12611424 ignition coil (top left) are used with 2005-newer cars, trucks, and vans. GM# 10457730 ignition coil (bottom right) and GM# 12558693 (top right) are used with 1999–2007 trucks and vans.
