That is why I used the GM 8-pin HEI module & coil in my 3 old Mopars. A factory GM cable connects the two. All you need it to supply 12 V IGN power, ground the module at its mounting screw, and connect the Mopar e-distributor pickup wire pair to the module using its connector (get polarity right, shine timing lamp at distributor reluctor wheel to assure teeth align when flashing). Tach output wire provided and can use extra connector to command spark timing (optional).
