* The factory coil from any vehicle that has a 12 volt negative ground electrical system and has a ballast resistor or resistance wiring in
the original ignition key wire will work with the MSD.
HELPFUL COIL INFORMATION
A ballast resistor is not necessary with any MSD Series Ignition but can be left in-line if originally equipped.
The MSD Blaster Coils and any other oil-filled, canister style coils should be mounted so that the high voltage coil
tower is pointed upward. Also, mount the coil so the coil wire is as short as possible to keep resistance low.
Use of any coil that is not compatible may damage the MSD and void the warranty.
