This harness is standalone and is not intended to replace the OEM engine wiring.  Standalone harnesses are intended to run the designated engine & transmission only, generally when swapped into another vehicle.  

 

This harness is designed for the 1999-2006 4.8L, 5.3L, 6.0L mechanical throttle body engines using an LS1 / LS6 PCM with a 4L60E, 4L65E, 4L70E, 4L80E, 4L85E, or manual transmission. 2003-2006 Engines will require a mechanical throttle body to be installed. 2003-2006 engines which were originally flex fuel will also require Delphi Multec 2 (factory truck style) injectors to be installed. Harnesses do not include connections for the rear O2 sensors or fuel tank pressure sensor but are available separate.

Included with this kit is an 0411 ECM PN 60718. This ECM has the VATS removed and is loaded with a 6.0/4L80E truck tune. Further tuning will be required by a local tuner.
