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.

      The ls1 swap..
    • SD619BLAZER73
      I used a old harness cut up at first . Bought a PSi harness. Can't compare how it runs. Dont make the mistake i did. Waist money. PSI is on it . Worth every penny. Quality.
    • Hotrodman 1972
      Was everything I was told it would be! I will definitely use this and other harnesses built by PSI.
    • Anyelo Garcia
      Works flawlessly, wiring looks as great as it works. Didn’t have any problems at all, installs easy and simple. Very knowledgeable and pleasant to work with. They will answer any question you may have. Great product. 
    • Whodoesit85
      This harness is amazing. It was easy to install, the instructions were on point. The tech team is great. My only issue was my MAF sensor was to short. I was able to buy an 18” extension, which I am ok with. I was hoping after spending what I did on my harness maybe I could have got it free of charge. Or at least free shipping… but definitely would NOT write them off for this! There product is amazing! Fired up on the first try

      We'll get you hooked up on the next one- let us know if you see us @ a show or order again - PSI

      PSI made it easy for me my first LS swap
      They know there stuff and wanted me to have a successful experience I shopped around nobody else had a complete harness and computer without using a bunch of cheap adapters and guessing game
