NOTES: These Harnesses are designed for retrofitting '14 - 22 LT1/L83/L86 GEN V engines from Camaro Corvette Suburban Tahoe Yukon Yukon XL Escalade Silverado Sierra into older muscle cars and street rods or newer non-emissions controlled vehicles. 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 Factory/OEM 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.
FANS: Fan control wires will only output signal depending on the operating system your ECM has. These wires are not guaranteed to control your fans. They will 100% not output signal when using a manual transmission. We offer the PAC-2800BT fan controller with Gen 5 harnesses for this reason.
ADDITIONAL ITEMS REQUIRED: E92 ECM, T43 TCM (6L80E), T87 TCM TCM (8L90E/10L90E) Your engine might have used a different ECM, our harness is designed to use the E92 ECM.
A T87A is required for Gen 1 10 speeds (pre 2019) while a T93 is required for Gen 2 (2019+) 10 speeds. The harness will plug into either TCM as they use the same plugs, there are no differences on the harness, only within the computers and computer programming.
* An OBD-II Speedometer / Tachometer (P/N STA-1000) is available from PSI to supply Tachometer, Speedometer and Check Engine Light
TRANSMISSION COMPATIBILITY:
6L80/90Es: Must be 2013+ model year transmissions to work with a Gen 5 LT system.
8L80/90Es: 2014-2018 gen 1 model years currently compatible. The gen 2 8 speeds (2019+) are currently not compatible.
10L80/90Es: All 2017-2018 Gen 1 10 speed transmissions are compatible. 2019-21 Truck/SUV and All 19+ Gm Performance and Camaro Gen 2 10 Speeds are compatible. 2022+ Gen 2 transmissions with the Electronic Transmission Range Select (ETRS) are not compatible. These ETRS transmissions will only have a "park" and "out of park" position on the external shift lever on the driver side of the transmission.
What sets a PSI harness apart from others in the market is a combination of tailored customization, American craftsmanship, and high-quality materials and construction standards.
- Tailored to Your Engine: PSI harnesses are not generic; they are specifically designed to fit your particular engine setup. This means you don't have to modify your engine configuration to fit the harness; instead, the harness is built around your engine combination. This customization ensures optimal fit and performance.
- Made in America: All PSI harnesses are proudly manufactured in the USA. This provides several advantages: stringent quality control, support for local employment, and adherence to high manufacturing standards. Customers can take pride in knowing that their harness is crafted by skilled workers using quality materials.
- High-Quality Materials and Construction: PSI harnesses use top-quality materials that meet or exceed OEM standards. They are built to endure the harsh conditions under the hood of a vehicle, including heat, cold, vibrations, and exposure to oil and gas. Key components like GM Delphi connectors and TXL high-temperature wire ensure durability and reliability. The use of "sonic welded" splices further enhances reliability by preventing the harness from coming apart.
- Customization and Small Volume Production: PSI offers the flexibility to produce customized harnesses in small volumes. This is beneficial for customers with unique engine applications or specific needs that may not be met by off-the-shelf products. This capability underscores PSI's commitment to catering to diverse customer requirements.
- Quality Assurance: Each harness undergoes rigorous computer testing using advanced equipment (Dynalab or Cirrus harness testing equipment). This ensures that every harness meets high-performance standards and reliability expectations.
In summary, a PSI harness stands out due to its tailored design, American manufacturing heritage, use of high-quality materials, customization options, and rigorous quality control processes. These factors collectively contribute to a product that is not only reliable and durable but also crafted with attention to detail and customer satisfaction in mind.
