About Performance Systems Integration
Performance Systems Integration (PSI Conversions) operates from Brick Township, New Jersey, at 2029 Route 88. The company traces its roots to the creation of its first standalone wiring harness over two decades ago, an innovative layout that simplified ground and power installation and became an industry standard for LS engine swaps. PSI manufactures LS and LT swap standalone wiring harnesses for GM Gen II, III, IV, and V engines, along with engine controller kits, transmission parts, and related conversion components. Harnesses are built using high‑temperature cross‑linked polyethylene TXL or GXL wire, with splices made on an ultrasonic wire welder and protected by high‑temp heat shrink. Power circuits use fusible link wire and individual fuses; harnesses are taped and loomed with high‑temp tape, F6 Pet braid, or Nylon split loom. Terminals and connectors meet or exceed OEM specifications from Delphi/Aptiv, Yazaki, and Kostal. Every harness undergoes 100% functional testing on computer‑based Dynalab or Cirris equipment. The company also assembles engine controller kits and provides PCM programming services. PSI’s product catalog covers a wide range of donor vehicles, including Chevrolet, Buick, Oldsmobile, Pontiac, Ford/Mustang, Nissan, Jeep, and Toyota platforms, as well as universal hot‑rod applications. PSI emphasizes domestic production, stating that its harnesses are made in the USA with top‑quality materials. It highlights a combined 25+ years of experience, phone support five days a week with 24/7 email access, and a commitment to shipping in‑stock harnesses within 1‑3 business days. The company’s original harness design is credited with setting the standard for the LS swap industry.
