Painless 1996-1999 GM Vortec 4.3L V6 (CMFI) Harness Extra. Length

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 1996-1999 4.3L Vortec CMFI engines with a 4L60E or 4L80E transmission. These engines were found in 1996-1999 GM full-size trucks and vans, S-10/S-15 trucks and SUVs, Chevy Astro Vans and Oldsmobile Bravadas. Harnesses do not include connections for the rear O2 sensors or fuel tank pressure sensor but are available separate. Included with this harness is an 8 circuit modular fuse block and GM color coded wires with labels for easy installation. 

This kit includes:

• All new fuel injection harness with OEM fitment connectors and harness breakouts.
• OBDII connector, mounting bracket and check engine light.
• Crimp on terminals and rubber grommet.
• Mounting hardware.

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

This harness also requires the following mating parts; ECM #16244210 or 16229684 with V6 programing.

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