GM IGNITIONS  GM Large Cap HEI Distributors
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 Tech Line (915) 855-7123.
