APPLICATION: 2008 - NEWER Corvette and Camaro LS3 Engines, LS3 GM CRATE ENGINES
PARTS INCLUDED: Complete Engine Wiring Harness (4 Wire Hookup), Programmed Engine Controller (ECM), Programmed Transmission Controller (TCM), Accelerator Pedal, LS3 Cartridge Mass Air Flow Sensor, Mass Air Flow Sensor Bung, Oxygen Sensors (Qty. 2), Oxygen Sensor Bungs (Qty. 2).
NOTES: This COMPLETE controller kit from PSI includes everything you need to get that LS3 engine and Overdrive Transmission running in your project vehicle. Why use an aftermarket controller for your transmission when you can utilize the Factory controller just like the original vehicle! The kit includes hardware and components that don't typically come with used engines, such as the wiring harness, mass airflow meter, pedal, oxygen sensors, oxygen sensor bungs, and programmed ECM/TCM - eliminating the need to source them separately. This controller system is a true stand-alone system for use in older vehicles, as all that's needed to get a vehicle running with it are power and ground sources, a 58-psi (400 kPa) fuel pump and an electric cooling fan.
These harnesses are designed for retrofitting '08 - '13 LS3 engines (Corvette, Camaro, Crate Engines) and 4L60E/4L65E/4L70E/4L80E automatic transmissions 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 Delphi Connectors and TXL (Polyethylene Cross Linked) High Temperature Wire to GM Specifications.
