For use with the ecu-GN only. Allows the use of individual coils, and the removal of the stock ignition module. The stock module will no longer be used, as the ecu-GN will control the coils directly. Includes relay and hotwire to alternator. The coils to use are AMP/EFI IGN1A, Holley Smart Coil, or Pantera. You will need a way to mount these. Recommend the LS coil setup in most cases (different harness), as these IGN1a coils are very powerful and can sometimes cause electrical interference.
