      We ordered this harness for a ls swap my shop was doing. We have tried many of the off brand chuneese versions out there. All we got with those were gremlins and headaches. With PSI and there swap harness it is always pinned properly and gremlin free. That saves me and my shop on bottom line. Must have for people who's time is valuable.

      I've used PSI products in the past on various LS swap projects. I've always been so impressed with the quality that comes with this product. Tech support is second to none. I prefer email because the tech support team is super busy but always replies in a timely fashion. Quit screwing around buying knock off chinese harnesses or building your own. Just get a PSI harness and save time and money.

      The sales rep was helpful, helped me get everything I needed on the harness. All connections were on and operable. Easy to install, the right length and my car started right up.

      I recently purchased my first standalone harness from PSI for my vortec swap into my 66c10.  It was an absolutely seamless experience, Bobby at PSI was extremely helpful and knowledgeable and helped me out with everything needed to make my swap work.  There’s no other choice but PSI in my opinion for everything LS swap related! ????

      I’ve ordered a few harness over the years from PSI. When ordering, take your time and make sure of injectors, maf and map sensors. If you order the right stuff, they work great.
