123 Ignition Wiring, This book is a collection of component installation procedures, applications and technical information. That is why we have assembled the MSD Ignition Wiring Diagrams and Tech Notes Book. Increase the reliability of your classic car with a 123ignition high performance electronic ignition for classic cars. The 123/TUNE+-4-R-V and the 123\TUNE+-6-R-V can be used on cars with ‘battery minus’ connected to the body of the car (this is also called “NEG-EARTH”), but also on cars with ‘battery plus’ connected to the body of the car (“POS-EARTH”). Wiring Diagrams and Tech Notes MSD believes that customer service does not end at just producing the best ignition components available, helping our customers is also a number one priority. 20,000+ diagrams for 600+ car models.
