This challenge led GM engineers to design the HEI ... ignition-control module, it can safely operate at much higher current loads. On a points-style distributor, the ballast resistor wire limits ...

The task previously accomplished by fragile points is taken over by a reliable solid-state electronic module ... HEI, be sure not to connect your new distributor to the ballasted resistor wire ...

If you have an AMC, a Ford, or a Chrysler distributor with a magnetic pickup, it's really easy to convert to a standard four-pin GM HEI module. We've included a simplified wiring diagram to show ...
