In this video we show an external HEI 4 Pin and talk about the basic benefits of HEI module conversion. For those looking for ECU controllable HEI modules, such as the 7 and 8 pin module, we have an upcoming video on the topic.
The HEI module information applies to almost all HEI conversions on Chrysler/Dodge/Plymouth Slant Six engines and V8s as well as Ford and Chevrolet Conversions.
