Universal fit: no vehicle restriction.
Most pre-1974 vehicles are equipped with OE resistance wires which limit the current for breaker point operation. PerTronix’s Ignitor II and Ignitor III ignition systems require a full 12V power connection between the ignition switch and the positive coil terminal. This requires bypassing the ballast resistor or resistance wire. In many cases, the original resistance wire is buried in the vehicle’s wiring harness. Adding a PerTronix power relay will eliminate the need to dig through the wiring harness and replace wires. Plus, the power relay guarantees maximum system voltage for more power.
