Harness allows use of the factory Vortec intake manifold and 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. Please contact PSI for more information.

      Amazing right from the box, “wire it up, fire it up” just like it says 
    • GTO Joe
      I purchased a harness and had to change direction of the project, PSI swapped out my harness to fit my needs!! Great customer service!!
    • guy with all the scouts
      This is my second harness/pcm set up i have bought from PSI, i have a 6.0 in a 73 scout and working on 5.3 to run in a 72 scout...the harness is super easy to install basically a plug and play, instructions are clear and easy to understand, there are other harnesses out there a little cheaper but so is the quality..i highly recommend a harness from psi..some things you dont want to cheap out on and a harness is at the top of the list.
    • BossMan
      Everything about this product is positive. The only issue I had was understanding that the new harness didn't have a transmission electrical plug. I thought that was a requirement for the transmission to not be in limp mode. I'll buy again
    • TP
      This harness was top notch. I LS swapped my C10 square body and it worked perfectly. My second LS swap, first one I did was a Holley Terminator X system which is a good product with the exception of the harness itself. Had several quality issues with the Holley harness causing lots of frustration. The PSI harness was hands down far better quality than the Holley. Had one technical question that I had to call tech support, had a call back from them in under 5 minutes. Great experience all around.
    • Plumcrazzie
      Nice harness plug and play. Easy good directions. Nice 4 wire hookup.
    • Bill
      I WAS TOLD TO HOOK IT UP, AND START IT UP. THAT IS EXACTLY WHAT HAPPENED. HOOKED IT UP, IT FIRED RIGHT, AND TOOK IT TO TUNER, RUNS GREAT.
    • Caddy man
      Perfect fit !! All wires and connections are correct, and has pre-wired relay for ignition and fuel pump.
    • Nick
      Great as always even afert customer told me wrong transmission application icalled you guy and was told it wasnt a big deal and that you guys would change that no problem it works great
    • Square body
      Not installed it yet but the quality looks great 
    • Flip
      Working great 
    • Gascan
      Simple instillation, easy to read instructions ,great customer service
    • Eli
      Wiring harness was well made and arrived fast. I had a problem with one of my sensors on the engine and the customer service was awesome and very helpful.
    • Drew
      Was a very easy install this is coming from a Holley user some of the wires had to be lengthened and some shorten but it’s not vehicle specific so that comes with it next time around I will do the softer loom just for appearance purposes 
    • John keeis
      Great product, labeled and all instructions very easy. Great customer service. Very helpful. 
    • Alan B
      Everything plugged in right and it all worked put it on the engine stand and it started up and ran for the test run all worked great
    • The Shoppe
      Very satisfied! I also purchase your products. They are quality products that always work. 
    • Vcook
      Well I really like the service I got when ordering harness but haven’t installed it yet so will let you know more when I get done 
    • Eric
      Really nice harness, only thing I found odd was I ordered a ls harness for a gen 3 Silverado setup and the maf wire was ran on the driver side not the passenger side ,so I had to get a extension harness 
    • R55CHEV
      I was told to just get an Amazon harness. Well I tried never doing a conversion before. After a few minor problems with the wrong fittings and very bulky plastic covers I decided to try a more expensive harness. The difference in quality and looks was immediately evident. This product is a definate step up and the tech support is available . I don't know about the durability but I expect it to last a very long time.
