    Default I/O Harness & Pin Map

    I AM HOPING DANNY WILL SEE THIS AND POST LINK.
    I AM CONFUSED ON HOW TO HOOK UP THE I/O HARNESS.
    DOES THE I/O HARNESS AND PIN MAP NEED TO BE THE SAME?
    ALSO IT TALKS ABOUT TRIGGERING OTHER THINGS.........SO CONFUSED

    Creating a custom Output:
    1st, Click on the I/O ICF and Outputs.
    2nd, Name it, select Type, Enable it & Configure it. Select the Switched/Sensor Input Triggers and activation criteria.
    3rd, It must be Pin-Mapped to an available J1 connector output pin; click "View Outputs" on the Pin Map.
    Then click & drag it to an available J1 Connector pin. Now you can run this wire to the relay.
    A relay must be used because all the ECU's Outputs are rated at a maximum of 2 amps.

    The 558-400 I/O Auxiliary Harness connects up to 4 Inputs & 4 Outputs to the EFI main harness.
    Eight Wire I/O Auxiliary Harness Connector Pin-Out (also in the Holley EFI Wiring Manual Link):
    Pin A...A12...White/Blue (Input #1)
    Pin B...A3...White/Red (Input #2)
    Pin C...A13...White/Black (Input #3)
    Pin D...A4...White/Green (Input #4)
    Pin E...B12...Gray/Yellow (Output #1)
    Pin F...B11...Gray/Red (Output #2)
    Pin G...B10...Gray/Black (Output #3)
    Pin H...B3...Gray/Green (Output #4)

    You're actually programming the ECU to assign a specific function to that pin/circuit.
    It doesn't have a specific assigned pin; it's any available Output pin, according to which Output Type you selected.
    Don't worry, the EFI software won't allow you to make a mistake with the Pin Map.

    If the I/O menu icon (ICF) isn't already uploaded (added) to the top Toolbar, follow these instructions:
    (This same procedure applies to all the various Individual Configuration menu icons/items.)
    The "I/O" function is an "Individual Configuration" of the Holley EFI software.
    At top of screen, Click "Toolbox" and "Add Individual Config".
    At top of new window, select "Individual Configuration Library".
    At bottom of new window, select "Holley EFI Inputs/Outputs Config".
    Select "I/O" and open "Base Config - Blank.io".
    The "I/O" icon will then be present at top of screen.
    May God's grace bless you in the Lord Jesus Christ.

    My problem was that someone set it up for me. But they had the Dominator, so I/O was different. Thanks Danny!

    I have the basic Super Sniper and my I/O J plug doesn't show up, just a bunch of stuff with green check marks, where I click on the tool icon. No pins to drag to and no way to assign pin to fuel pump #2?

    Can you attach a screenshot of what you're talking about?

    The screen with the green check marks is the Pin Map. If you've enabled the Secondary Fuel Pump in the Basic I/O, then it'll show up in the Pin Map when you click on "Outputs". From there you can assign it to any appropriate pin. Andrew
