Ford and Plymouth, installed four-cylinder engines in their cars.he increased efficiency of HEI distributors stemmed from the incorporation of the ignition wire into the distributor cap, reducing degradation of the spark and loss of energy potential.

Disconnect the 12 volt keyconnector, the 3-wire connec-tor coming out of the distributor andthe Tach Connector (if applicable).2.Connect the Pink, Black and oneof the Brown wires of the Harnessto the corresponding wires of the3-wire connector coming out ofthe distributor.3.onnect the Red wire of theHarness to the key connector.4.
