      As a novice LS swap enthusiast, I was very impressed with my PSI harness. It made wiring up my donor very simple and super clean. I was able to select all the pertinent options for my specific package, so it was literally plug-and-play. Very detailed directions and great support made it a no-brainer.

      The harness is worth the money and once I made the hole through my firewall and fed the wires through, I see it really looks good.

    • Mike76

    • SteveS
      I purchased this harness to replace a bad one from another manufacter. It was great and easy to install.
    • Crew454
      Harness worked great, staff easy to deal with, I would not hesitate to use PSI again.
      The only thing I was not expecting was the harness was assembled to fit inside the cab. Had I of known this I would have requested ECM mounting designed to mount on rad core support and fuse box inside cab.
    • Repski
      I bought a cheap harness off eBay and had nothing but problems. Bought from PSI, installed it and the truck fired up without issue. PSI is thorough with the questions about your vehicle which avoids unnecessary problems.
