    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

      This is my second harness with psi. Both times they are patient with my questions and answer them with reassuring knowledge. My first harness and tune had me scared of my car! I did 100 burnouts through all three gears! They did the tune on a bench! The harness got damaged and I had to upgrade the transmission to a t56. They tried to fix my old harness but they have too many updates to it. They took amazing care of me as a second customer and made it an easy decision to get and new one. I recommend the braided housing. It looks amazing! These guys are great!

      I have had many harnesses and PSI is the best harness out there easy install and looks factory and plugs in like factory. My tuners in NJ and NC even says these guys make good products! Overall super happy with my two harnesses and computers, about to order another one too!

      This thing is legit. I suck at wiring and initially tried to rework my gen3 lm7 harness myself for my swap. It wasn't going good. It technically worked but I'd feel nervous to drive it further than to work. A shop advised me to get this harness for reliability and appearances and it was well worth it! Fantastic quality, labeled really well, and it came 4 days after I ordered it!
