This section covers the MSD Digital-6 Plus and the Digital-7 Plus. These ignitions share the same wiring and functions. The main difference is that the Digital-7 Plus produces more spark energy and is intended for racing applications only. The 6 Plus is designed for street/strip use and even carries a CARB Approval Number.
Both ignitions will install to most vehicles with a 12 volt electrical system and a distributor that is triggered with points, electronic amplifiers or magnetic pickups.
