    Found some more nors made in USA real ECU's, boxes are trash and wont be shipped. All tested fine. Asking $45 shipped lower 48. Used on most 72-79 applications


    The only difference in the circuit / ECM with the dual ballast is that the second ballast resistance feed power into the 5th pin on the ECU. That is no longer used, and unless you find a really old original vehicle or really old NOS, most any new ECU WILL be 4 pin.

    You can use a 4 pin box in a 5 pin harness, but not the other way around

    Does this box eliminate the dual ballast?

    No you still need the ballast. It is a stock repacement.
