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 models may experience a hesitation or stall
on deceleration. If this occurs, contact MSD Tech Line
for the required bolt-in diode to correct the problem. MSD
