    • OMG, where have you been
      I don't know where to start. I had an old harness reworked and all I did was fight with the vehicle and everything about it. I had problems with model numbers, intake, throttle drive by wire, and a few other applications that just did not make sense. When ordering a new wiring harness from PSI it became perfectly clear that they not only had all the information that I needed, but they also modeled numbers of different parts, everything became so much easier. Not only did I get an excellently made wiring harness, I also received a sheet with all the information for all the other parts that I need to put my motor together and make this possible. The ordering was very simple and the representative was extremely knowledgeable. If I had to do it all over again I would have just called PSI in the 1st place and asked what would be the best application for what I'm trying to build. In a nutshell, the LS swap went very well once I got my parts from PSI. Every single connector had just enough length to connect to what I had on the engine. I cannot say enough about PSI the tech the equipment and the overall experience please thank your entire PSI team that made this build possible for me I appreciate your patience your expertise and knowledge. Happy holidays.

    • My Harness
      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

    • Can't go wrong on your project with PSI.
      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.
