ORIGINAL BALLAST RESISTOR WIRING WITH
A BLASTER IGNITION OR MSD 5 IGNITION
The MSD 5 and Blaster Ignitions are inductive ignitions which enhance the spark of the vehicle’s
stock ignition. The MSD 5 is a multiple spark ignition, while the Blaster is a single spark, long duration
design. Both are designed for entry level and budget build-ups and can be triggered with points or
electronic ignitions. The Blaster can also be triggered by a magnetic pickup distributor such as the MSD
Pro-Billet Distributors.
Ballast Resistors: If the vehicle has a ballast resistor or resistor wiring leading to the coil,
leave it inline and connect the Red wire of the ignition before the resis-
tor. If there are no resistors originally, the Blaster Ignition and MSD 5
do not require it. For aftermarket coils, use the coil manufacturer's
recomendations.
NOTE: Not recommended for use with a GM HEI Internal Coil Distributor.
Wire F unctions

Black: Connects to ground.
Orange: Connects to the negative (-) terminal of the coil.
White: Connects to the points or electronic ignition amplifier output.
