    NOTES: These Harnesses are designed for retrofitting '99 - '03 Vortec engines (4.8, 5.3, 6.0, 6.2-Liter) and T56 or non-electronic automatic transmissions with LS3 intake manifolds into older muscle cars and street rods or newer non-emissions controlled vehicles. Harness allows use of the LS3 intake manifold and EV6 Injectors. They are completely plug and play with four wire hookup (switched power, constant power and ground connections required). Harnesses are designed with a sliding grommet seal and 4 - 5 feet of length from the rear of the cylinder head to the PCM mounting position under the vehicle dashboard. A sliding grommet seal allows for professional, leak proof installation.

    Harnesses are professionally constructed from Brand New GM Delphi Connectors and TXL (Polyethylene Cross Linked) High Temperature Wire to GM Specifications. All Harnesses are 100% Quality Inspected prior to shipping. All Harnesses require PCM VATs removal, available through PSI. Please contact PSI for more information.

    • Classic Joe
      The wiring harness was easy to install plug and play per the instructions. Matched with PSI computer it started and cycled to idle immediately. Very Happy with this system !!!

      This harness was perfect and made wiring up my LS swap a breeze. The quality and cleanliness is amazing and looks better than OEM. PSI is also a great company to deal with as well. They cover all the bases and ask every question when it comes to nailing down exactly what harness your project needs. They know what they’re doing when it comes to LS harnesses and it shows. Can’t recommend them enough.

      After lots of difficulty from another vendor, someone referred ne to PSI. And, as promised, I was able to simply wire it up and fire it up!!!
