This harness has been made by MSD to correct a check engine light issue that can arise in vehicles using the MSD LS Coil Packs on their engines. This harness will supply additional battery voltage to the coils in order to fire the coils properly and not drain other engine systems of power. This is necessary due to the varying wire gauges used on production vehicles.
