    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 LS1 intake manifolds into older muscle cars and street rods or newer non-emissions controlled vehicles. Harness allows use of the LS1 intake manifold and EV1 injectors and the factory 5 pin MAF sensor. 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
