Description

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.  

Painless LS swap wiring harnesses make getting your engine swap wired a simple task!

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 the 1998-2002 Camaro/Firebird. This harness will also work on 1997-2004 Throttle By Wire (TBW)  LS1/LS6 engines which have been changed to mechanical throttle bodies or any 1999-2006 (4.8, 5.3, & 6.2) Vortec truck engine that 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 separately. Included with this harness is an 8-circuit modular fuse block and GM color-coded wires with labels for easy installation.

This standard-length harness allows four feet from the back of the intake manifold to where the fuse block and ECM mount. Perfect for those who plan to mount these components under the dash or in the glove box.

This kit includes:

  • All new fuel injection harnesses with OEM fitment connectors and harness breakouts
  • OBDII connector, mounting bracket, and check engine light
  • Rubber grommet
  • Mounting hardware

We recommend checking the online manual for the full list of required mating parts prior to ordering.
