    NOTES: These Harnesses are designed for retrofitting '03 - '07 Vortec engines (4.8, 5.3, 6.0-Liter) and 4L60E or 4L80E transmissions into older muscle cars and street rods. Harness allows use of Multec Injectors with flex-fuel Injectors (EV6) optional. They are completely plug and play with four wire hookup (switched power, constant power and ground connections required). Harnesses are designed with a sliding grommet seal and 4 - 5 feet of length from the rear of the cylinder head to the PCM mounting position under the vehicle dashboard. A sliding grommet seal allows for professional, leak proof installation.

    Harnesses are professionally constructed from Brand New GM Delphi Connectors and TXL (Polyethylene Cross Linked) High Temperature Wire to GM Specifications. All Harnesses are 100% Quality Inspected prior to shipping. All Harnesses require PCM VATs removal, available through PSI.

      Ordered my harness a few months back after trying to modify a stock harness myself. Harness came in and was oem quality with excellent length for a connections needed to my engine. Directions very clear. Will be buying another harness for my next ls swap

    • Mike W
      It was very well packaged. Great work sheet of product. Easy to install. Engine fired right up with no issues. 
    • Money
      Harness worked great, only thing is it could be a little bit longer. I never mount the PCM and fuse box inside because there's just no room to mount them inside especially trucks. So I always try to mount them close to where the factory mounts them. Other than that it works well. Sometimes the wire to the maf are too short because your really dont know which side the cold air intake will be .
    • guy with all the scouts
      well did my 1st LS swap into a scout 2, bought a bargain deal harness and pcm from a fella that did them as a side Hussle (wrong had nothing but problems) so i decided to buy a complete harness and pcm from psi, routed my wires hooked everything up and BAM engine fired up and runs great! i highly recommend buying a harness and pcm set up for your project..it will save you hours of frustration...73 IHC scout 2 with a 6.0/4l80/np241...like all LS swaps you will still need to have it fine tuned
    • Hillbilly
      First class work harness fits like it should look great plug an play
    • JMac
      PSI was recommended by a friend who has experience with other harness makers. At first I thought your price was a little high but being an industrial electrician for 35 years I know you usually get what you pay for. I installed the harness in just a few hours by myself and it looks great. I will also recommend PSI to anyone in the future. Thanks for making my first swap so easy!
