  • The PSI Conversion Holley Harness was designed as an upgrade, to provide customers with a much more efficient, higher quality harness to simplify installation. PSI Holley Harnesses are built in house in the USA with GM spec high temp cross-linked polyethylene TXL wire. Terminals and connectors meet or exceed OEM specifications from Delphi/Aptiv, Yazaki, Kostal etc. All harnesses are 100% quality tested using Dynalab or Cirrus harness testing equipment. These harnesses are built to YOUR engine and do not require the bulky sub-harness connections like the Holley harness does. Automatic trans control, drive by wire control, and injectors are all built directly into the harness. 

    PARTS INCLUDED: The PSI Holley controller kit comes standard with the complete harness as optioned, wideband oxygen sensor, 3.5in Holley LCD screen, Terminator X (X MAX as upgrade), and Holley CAN cable. Drive by wire kits will also include the ACC-1007 Corvette pedal. 

    APPLICATION: The PSI HAR-HOLLEY harness can be ordered for any 24x (Gen 3) or 58x (Gen 4) LS & vortec engines (1997-2015+), drive by cable or drive by wire throttle control, and 4L60 (1996+), 4L80 (1993+), or non-electronic and manual transmission applications.

    NOTE: Terminator X MAX is required for drive by wire throttle control and/or 4L60/4L80 transmission control.

    The Terminator X ECU features real-time fuel learn, high impedance injector drivers, an integrated 1 bar MAP sensor, and 4 programmable inputs and outputs. The inputs and outputs are ideal for electric fans, boost control solenoids, progressive nitrous control, and much more. Terminator X comes fully loaded with base maps for common LS engine combinations to get you out of the garage and on the road/track fast.

    When to use a Holley ECU over a factory GM ECU?

    • Holley computers are recommended for use in race car applications where tuning may be updated or changed frequently for different race applications or tracks as well as frequent drivetrain changes.

    Does a Holley ECU require custom tuning?

    • All Holley computers must be set up with the Holley setup wizard to base map the tune on your engine. This can be done on the 3.5in Holley LCD screen or on a laptop. This base map is a self learning/adjusting tune that will get your engine fired up and running, however a custom tune from a professional tuner is always recommended for built engine applications to optimize performance.
