Painless Performance 60715 EFI Harness with VATS Removed ECM for 1998-2004 GM LS1/LS6

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 1998-2002 LS1 mechanical throttle body engines using a 1999+ LS1/LS6 ECM with a 4L60E/4L65E/4L80E automatic or T56 manual transmission. These engines were found in 1998-2002 Camaro/Firebird. This harness will also work on 1997-2004 Throttle By Wire (TBW) LS1/LS6 engines which has been changed to mechanical throttle body or any 1999-2006 (4. 8, 5. 3, & 6. 2) Vortec truck engine which has been changed to a factory of aftermarket LS1 intake manifold, mechanical throttle body, and injectors. Harnesses do not include any emissions related connections but are available separate. Included with this kit is an 0411 ECM Painless Part #60717. This ECM has the VATS removed and is loaded with a base LS1 Camaro/Manual Trans tune. Further tuning will be required by a local tuner.
