    Yes, a Terminator X ECU is compatible with the HP/Dominator main harness.

    Well, I got the final say from Holley, my ECU is toast. They couldn't say what went wrong, but they are sending it back to me. Overall, they have been nice about it and tried to help. So I guess a new ECU is in order. Thanks for all the input. BTW, Does anyone know the failure rate on thee Holley ECU's? Larry

    UPDATE #6: With the online help of AndrewB, the new HP ECU is in the car & tuned. I'll take it out for a test ride today, but I have every expectation that all is well now. I still have no indication why the original ECU failed. It was a very early model, maybe that had something to do with the failure. Thanks again to all who helped.
