PSI standalone LS/Vortec engine and transmission harness for a Holley Terminator X system. This fixed setup is for Gen 4 58x engines, drive-by-wire throttle, a manual or non-electronic transmission, and EV6 injectors.
Made in the USA from SAE-1128 high-temperature TXL wire with terminals and connectors built to OEM standards. PSI tests every harness before it leaves, so the swap wiring is handled without building a harness from scratch.
Complete engine and transmission harness plus instruction manual included. Holley Terminator X or Terminator X Max ECU required. Part PSI-HOL-G4M-EV6W.
