Thread: Terminator Stealth Ignition Questions

    Danny, I just off the phone with Anthony from Holley Tech. Very nice guy. He explained the Stealth and the X are different and the Stealth will not plug into the HyperSpark like the X will. For the Stealth, the Dual Sync is plug in ready. The adapter 558-323 is not going to help me.

    He said I can cut connectors and wire the Hyperspark in, if I knew what I was doing, but I don’t so, that seems like a dead end for me.

    I’m not keen on the Dual Sync so I may opt to not have the ECU control my timing and pick another distributor. I need to figure out what I want to do. I didn’t think this part of it would be this difficult. Joe

    I think it will work, but I just don't have the details to explain it all.
    May God's grace bless you in the Lord Jesus Christ.

    I did this swap when the HyperSpark distributor first came out. There's only three wires in the ignition connector that you'll need to use. Pins A, C & E:
    Pin A A30 purple crank input +.
    Pin C A14 green ipu ground -.
    Pin E A10 red/white 12 volt switch.

    Distributor pins A, B & C:
    Pin A 12 volt switch.
    Pin B purple +.
    Pin C green -.

    The connector coming off the distributor will go like this:
    A will go to E.
    B will go to A.
    C will go to C.

    You'll need to cut the 2-wire connector off the suppled harness, this comes with the distributor. You can see the connector in the third picture:

    You'll need a couple of Metri-Pack pins, Holley sells them.

    I'm helping a friend with a Terminator Stealth install with a Holley Dual Sync distributor, remotely, and just so I'm clear:
    The Terminator Stealth ECU needs to be tuned with a laptop, and it's not possible to configure the Dual Sync distributor with the handheld?
