This standalone harness is not intended to replace the OEM engine wiring.
Intended for running the designated engine & transmission only, standalone harnesses are generally used when swapped into another vehicle.
Designed for 1996-1999 4.3L Vortec CMFI engines with a 4L60E or 4L80E transmission, these engines were found in GM full-size trucks and vans, S-10/S-15 trucks and SUVs, Chevy Astro Vans, and Oldsmobile Bravadas from 1996-1999.
Connections for the rear O2 sensors or fuel tank pressure sensor are not included but are available separately.
An 8 circuit modular fuse block and GM color coded wires with labels for easy installation are included with this harness.
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, rubber grommet, and mounting hardware.
This standard length harness allows four feet from the back of the intake manifold to where the fuse block and ECM mount.
For those planning 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 programming.
Checking the online manual for the full list of required mating parts prior to ordering is recommended.
