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
