Harness allows use of the LS3 intake manifold and EV6 Injectors. 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.

    ADDITIONAL ITEMS REQUIRED: RED/BLUE PCM (SERVICE NUMBER 411 or 896), PSI P/N PCM-1003.

      Well, PSI saved the day. Been working on a 6.0 swap on my 66 GMC panel. Took the knucklehead route to save some bucks and went the Amazon/China route for the standalone computer harness. $300 bucks- wired wrong, car wouldn’t shift, had a short and huge misfires. 3 weeks trying to diagnose, tune and change parts- we ultimately found the cheap harness was bad. I called PSI crying, tech in the phone was amazing. Walked me through the order and expedited for me- he probably felt my pain. The harness was quick to install and fixed all my problems- laid a fat burnout in front of the house- my wife said thank you! Lol thx again PSI

      This was my first LS swap and the wiring went smoothly. Read and follow the instructions. This is a great harness, a little pricey but the car fired 1st turn of the key. Instructions for the TCC brake switch could be better. Customer service was great.

      II have used psi for yours on all my customer builds, sales are very helpful, the products are well done, orders are shipped quickly and a very important extra is, when I call tech for a question they are experienced and helpful, and within a timely manner 
      Highly recommend psi for all your swap needs
