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.
