    Dominator Auxiliary Harnesses: https://www.holley.com/products/fuel...efi/harnesses/

    To connect up to 4 Inputs & Outputs to the EFI Main Harness, use I/O Auxiliary Harness 558-400.
    Eight Wire I/O Auxiliary Harness Connector Pin-Out (also in the Holley EFI Wiring Manual - LINK):
    Pin A...A12...White/Blue (Input #1) F,5,2,T,H,G
    Pin B...A3....White/Red (Input #2) F,5,2,T,H,G
    Pin C...A13...White/Black (Input #3) F,5,G
    Pin D...A4....White/Green (Input #4) F,5,G
    Pin E...B12...Gray/Yellow (Output #1) H,P+
    Pin F...B11...Gray/Red (Output #2) H,P+
    Pin G...B10...Gray/Black (Output #3) G,P−
    Pin H...B3....Gray/Green (Output #4) G,P−
    http://documents.holley.com/199r10516.pdf (Holley 558-400 I/O Auxiliary Harness Instructions)

    The 558-400 I/O Auxiliary Harness is 20 feet long.
    It's "plug & play" into the main harness, and an easy way to connect common things like an electric cooling fan (LINK).
    This I/O Auxiliary Harness isn't required for the optional oil & fuel pressure transducers, which are also "plug & play" into the main harness.
    The oil & fuel pressure transducers are used for Data Monitoring, Data Logging and setup Outputs based on oil & fuel pressure.
    NOTES:
    • Installing, removing & relocating (pinning) the ECU connector terminals is easy. No special tools involved.
    Push the single wide white tab to release the lock (on all terminals), and push the two narrow white tabs to re-secure.
    Holley has the P2A, P2B, P3, P4 and other auxiliary harnesses available:
    https://www.holley.com/products/fuel...efi/harnesses/ (Dominator ECU Auxiliary Harnesses - Check Mark "Auxiliary")

    • The harness connectors are Delphi Metri-Pack 150 Series connectors.
    Some of the sensor connectors are Delphi GT 150 Series (with the different colored "key index" insert).
    http://delphi.com/manufacturers/cv/c...ck-connectors/ (Delphi Metri-Pack 150)
    http://delphi.com/pdf/contact/brochures/DCS_GlobalCatalog.pdf (Delphi Global Connection Systems Catalog)

    • I use the same tool for crimping Metri-Pack, Weather-Pack & SuperSeal terminals (ECU connectors).
    This crimping tool is my favorite, is inexpensive, and works very well:
    http://www.whiteproducts.com/tools.shtml (T-18 Metri-Pack/Weather-Pack Terminal & Seal Crimper)
    http://documents.holley.com/199r11022.pdf (Holley EFI 567-100 ECU Connector Terminal Crimper)

    • If you're also working with Weather-Pack connectors, the terminal release tool is a necessity:
    http://www.whiteproducts.com/removal_tools.shtml (T-3 Weather-Pack Terminal Release Tool)
    http://www.innovatemotorsports.com/x...0&cat=0&page=6 (Nice Kit From Innovate Motorsports)

    • If you don't have the actual Metri-Pack terminal release tool, a "safety pin" will work.
    It just needs to be a stiff wire between .030"-.035" in diameter to release the terminal tab.
    Then reopen (bend) the terminal tab before reinsertion, so it will clip (lock) into the cavity.
    http://www.whiteproducts.com/removal_tools.shtml (T-6 Micro Terminal Pick Release Tool)

    • I always use the 16/18 AWG (1.0-0.80 mm²) terminals for Metri-Pack 150 and Weather-Pack connectors.
    If using the smaller diameter 20/22 AWG wire (0.50-0.35 mm²) in a 16/18 AWG terminal, simply strip off twice
    the amount of insulation you normally would, and fold it in half into the larger terminals for proper size crimping.
    http://www.engineeringtoolbox.com/aw...uge-d_731.html (AWG to mm² Wire Conversion Table)

    • Not for ECU or other specialty terminals (Tyco, Amphenol, Deutsch, Metri-Pack, Weather-Pack, etc.), but I'll include it here:
    For crimping conventional butt, spade & eyelet connectors, these are the best tools I've used: Insulated & Non-Insulated.
    (Ideal Industries sold the same insulated terminal tool #30-425 as Snap-On PWC30. Currently discontinued, but may still be available.)

    • For crimping large AWG cables (battery/main power), the Quick Cable Cub Crimper #4245 is an excellent tool (LINK).
    Basically, the Quick Cable Cub Crimper continues (8 to 1/0 AWG), where convention hand crimpers stop (10 AWG).
    FYI: When using the Cub Crimper on battery lugs, it works best using a "two crimp" method. First crimp with the next larger size die
    than specified, then final crimp with the correct size die specified. The rotating dies are an integral part of the tool; easy to adjust.
    May God's grace bless you in the Lord Jesus Christ.

    Hi Danny, do you have the connector and terminals source for the MAIN POWER cable? The Holley one is a bit pricey (already got mine) but for the Metri-Pack connector for the ECU cavity, the rest is just wire, and a fuse holder? Thanks, Frank.

    That's a Delphi Ducon 6.3 Series female connector assembly.

    Danny, do you have a link to the pins & connector if I wanted to make my own 558-400 harness?

    The 558-400 I/O Auxiliary Harness connector is a black, eight cavity Delphi Metri-Pack 150 Series connector with eight male terminals.

    I need to make a pigtail for the CTS sensor, what's the connector for the CTS on the HP harness?
    Need to do the same for the IAC on Holley's throttle body, do you know that as well? Thanks.

    The CTS, MAT/IAT & flat 4-pin IAC connectors/terminals are the Delphi Metri-Pack 150/150.2 "Pull-To-Seat" type.
    #12048074 16/18 AWG (1.0-0.80 mm²) Metri-Pack 150 terminals.
    #12084200 20/22 AWG (0.50-0.35 mm²) Metri-Pack 150 terminals.

    The Delphi Metri-Pack 150.2 terminals have a flag for the slotted connectors. See posts #10 & #30 for more info.
    #12124075 16/18 AWG (1.0-0.80 mm²) Metri-Pack 150.2 "Pull-To-Seat" terminals.
    #12124076 20/22 AWG (0.50-0.35 mm²) Metri-Pack 150.2 "Pull-To-Seat" terminals.

    Thanks Danny, good thing I asked because I didn't think it was the pull-to-seat style.
    Another question, I can't find the other mating end, I'm assuming that would be the male end. Do you know if and where they are available?
    I want that end too so I don't have to modify the main harness. I want to do a test with two IAC vs one on my blower setup.
    Also, what is the black covering Holley uses for the harness? I need to cover the DIS coil wires and wanted it to match. Thanks.

    Some of those mating ends (Metri-Pack 150/150.2 "Pull-To-Seat" connectors) don't exist, because they plug into sensors or actuators.
    Exception: Round 3-pin TPS female mating connector - Delphi 2120-0554 (motorcycle & powersport applications - LINK & LINK).
    Exception: Oval 2-pin CTS female mating connector, black - Delphi 12066016 (solder & shrink tube required LINK).
    Exception: Oval 2-pin MAT female mating connector, gray - Delphi 12084669 (solder & shrink tube required LINK).
