There are three different large cap HEI distributors. To identify which
of the following diagrams fit your specific application, remove the
distributor cap and rotor and locate the ignition module at the base
of the distributor. Count the number of terminals on both ends of
the module and follow the corresponding diagram. GM used 4, 5,
and 7-pin modules in these distributors.
NOTE: Some 5-pin modules may experience a hesitation or stall on
deceleration. If this occurs, contact the Mallory Technical Service
Department for the required bolt-in diode to correct the problem.
