    Take the fear out of electronic fuel injection! These engine wiring harnesses are designed to make your engine transplant effortless. Each new harness contains in-depth application-specific instruction sheets, clearly marked factory GM connectors, labeled GXL jacketed wire, GM color coding, and pre-fitted corrugated slit loom for an extra value and professional look. All un-needed emissions wiring is eliminated to make the install as simple and reliable as possible.

    • Made from premium grade GXL jacketed automotive wire
    • Most wiring is larger gauge than stock application for durability
    • No splices to reduce points of failure
    • All primary grounding is done at the head or block and grounding points are isolated from each other to reduce electrical interference and minimize ground looping
    • Harness wiring matches GM wiring configuration and jacket colors follow GM color coding for easy identification
    • All electrical connectors are made by Delphi or Packard and are direct fit for GM cars and trucks
    • Can be installed to run engine in 20 minutes, but figure 4-6 hours for a professional installation
    • Diagnostic connector or OBD2 port for connection to scanners and tuning tools


    This harness is covered under warranty for the lifetime of the original owner against defects in workmanship within the wiring harness only, not time, or any damage in result of defective workmanship of the wiring.
