Painless 1999-2006 GM Gen III 4.8 - 5.3 & 6.0L Harness Standard Length

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.

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 harness is a 10 circuit weatherproof 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 that plan to mount these components under the dash or in the glove box.

This kit includes:

  1. All new fuel injection harness with OEM fitment connectors and harness breakouts
  2. OBDII connector, mounting bracket and check engine light
  3. Rubber grommet
  4. Mounting hardware

**Please note that this harness does not support Flex Fuel USCAR Injectors.**
We recommend checking the online manual for the full list of required mating parts prior to ordering.

What year ecu (computer) would I need for this harness to plug into? 99-02 or 03-06???

Asked by: Colton
according to this harness being equipped for a mechanical throttle body a 2006 model ecm would not be compatible due to the 2006 models having an electrically operated throttle body. The fact that someone is specifically asking whether to use a 99-02 ecm which is set up for mechanical throttle body or an 03-06 ecm which is set up for and electrically operated throttle body and your response as a vendor of this product is that they will need an ecm for a 99-06 shows the lack of knowledge and customer service that will be received through this company.
