Simple 4 pin hei wiring

The 7 Pin HEI Module. With a GM HEI 7-pin (and 8-pin modules), the ignition module wires you need to know about are: tach signal is a purple wire with a white trace [pin R] goes to Ampseal OPTOIN+

pin #30 (ground the Ampseal OPTOIN- pin #31 at the distributor) ; advance control signal is a white wire [pin E] goes to Ampseal pin #12; override (cranking) signal is a tan wire with a black trace General Motors HEI Ignition Control with MegaSquirt-II. There were a number of different kinds of General Motors HEI modules: 4 pin module - electronic ignition, but doesn't do computer timing control, top left; 7 pin module (large) - electronic module that does timing control, used with coil-in-cap distributors, top right; 7 pin module (small) - electronic module that does timing control Best gallery images for wiring diagram, wiring harness, electrical diagram, engine diagram, parts diagram Find MSD Street Fire HEI Distributors 8362 and get Free Shipping on Orders Over $99 at Summit Racing! These MSD Street Fire HEI distributors are packed with high-quality features and components. These distributors use a centrifugal advance

assembly with coated weights and welded weight pins (not just pressed in). The Street Fires are fit with the same gear that is used on MSD Pro-Billet models. Notes: For the pressure control (PC) solenoid: You need a minimum 4.7 Ohm (or higher resistance - up to ~10 Ohms), 10 Watt (or more) resistor (such as Digi-Key 4.7CWBK-ND, $1.67) on the pressure control solenoid wire from the trans connector pin D to the GPIO board's pin 33. This resistor dissipates up to 4 Watts of power at low line pressures (maximum PWM percentages).
