    • 1019 Harness
      The guys at PSI were very helpful when it came to picking out the harness I needed. Especially since I had a mix/matched combination. It is outstanding quality! The last swap I did I had the harness cut down and ended up having to make my own fuse panel and all. Such a nightmare. Glad I went with The PSI harness. Highly recommend and will definitely being using them again on future ls swaps!

    • Can not say enough about the whole expirience.
      There might be other products out there for less, however the product support Can NOT be beaten. There are alot of issues when swapping any modern engine into any vehicle and even a seasoned pro needs a second opinion to ensure its all being done right. The answers come from PSI's team and they come fast n friendly. Thanks to everyone at PSI.
