    • Best harness on the market
      I will highly recommend PSI harnesses to any, and everyone doing an LS or LT swap. The ease of product use the complete construction of the harness and the customer service is second to no one in the aftermarket automotive electrical community. I installed the hardness and had the truck running in half a day. Thank you to the team for the quality parts and customer service. John Bear.

    • Best harness for the money
      There are cheaper harnesses a available and I wouldn't put one on one of my vehicles if they were free. PSI builds a great product at a fair price. After trying several others, PSI is the only supplier I use now.

    • Better off buying the PCM to go with it.
      The harness has great quality, simple set up and looks great! Definitely recommend to anyone doing a swap anywhere from a first timer that's not great with wiring to a seasoned pro that wants to save time.

    • LS standalone harness and ECU
      Customer service was great, Glad I decided to go with their harness and ECU. Peace of mind ain't cheap, but at least I have peace of mind that the harness and ECU won't leave me stranded along the side of the road.

      I have used 3 harness from PSI and every single one was great and I had no issues. Even when I had questions customer service was fast to respond and quick to give advice on the best route to go on a swap. Great product and company over all!

    • pretty good
      good instructions, easy to wire up, its basically plug n play. It gets expensive when you start adding all the things you need but I don't know how much id be somewhere else. my tuner recommended me this site so I just went with it without much research. overall its a good product, you get what you pay for. ls1 swap into a 70 nova if you wanted to know.
