PSI Conversion PSI-HOL-G3M-EV6W Details

Holley Terminator X LS Standalone Harness | PSI Conversion

APPLICATION: Fits Gen 3 LS and Vortec engines with a 24X reluctor wheel, a drive-by-wire (DBW) electronic throttle body and pedal, and a manual or other non-electronic transmission (T56, T5, TR6060, or non-electronic automatic).

PARTS INCLUDED: Complete engine harness, instruction manual.

ADDITIONAL ITEMS REQUIRED: Holley Terminator X MAX ECU (554-153). Terminator X MAX is required for drive-by-wire throttle control.

The PSI Conversion harness was designed as a higher-quality alternative to the standalone harnesses currently available, focusing on better components, greater efficiency, and a simplified installation. Every harness is built in the USA using SAE-1128 spec high-temp cross-linked polyethylene (TXL) wire, with terminals and connectors that meet or exceed OEM specifications from Delphi/Aptiv, Yazaki, and Kostal. All harnesses are 100% quality tested on Dynalab or Cirrus harness testing equipment.

The Terminator X MAX ECU features real-time fuel learn, high impedance injector drivers, an integrated 1 bar MAP sensor, and four programmable inputs and outputs that are ideal for electric fans, boost control solenoids, and progressive nitrous control. It ships with base maps for common LS combinations, and the Holley setup wizard builds a self-learning tune to get the engine running. A custom tune from a professional tuner is still recommended on built engines.
